PREMASGARD® 211x ⁄ 212x ⁄ 212x – SD Rev. 2021 – V21

The calibrateable compact pressure sensors of the PREMASGARD® 211x ⁄ 212x ⁄ 212x – SD series are equipped with 8 switchable measuring
ranges, 2 switchable output signals (16 devices in one) and with or without optional display and are used for measuring above-atmospheric, below- atmospheric, or differential pressures and Volume flow in air. The piezo- resistive measuring element is temperature-compensated and guarantees a high degree of reliability and accuracy. These pressure transmitters have a pushbutton for manual zero point calibration and an adjustable offset.
Applications of these pressure sensors are in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, in large-scale catering facilities, for monitoring filters, for level measurement or for triggering frequency converters. Media measured with these pressure transducers are air (non-precipitating), or other gaseous non-aggressive, non- combustible media. The differential pressure sensor is supplied including connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws). You can find further device types under PREMASGARD® 111x ⁄ 112x ⁄ 112x – SD (l variant with 2-wire connection).

PREMASGARD® 211x ⁄ 212x ⁄ 212x – SD | Configuration and zero point calibration

The following configurations can be preset via  DIP switches.

The DIP switch sliding blocks can be moved  without using tools. DIP switch 6 is not assigned.

Pressure ranges

In each case four different pressure ranges  depending on the type of device can be preset  via DIP switches DIP1 and DIP2.

Measuring range mode

The measuring range is configured via DIP  switch DIP3, either into the unidirectional range or into the bidirectional range.

Therefore altogether eight pressure measuring  ranges are configurable.

Characteristic line – analog output

The output characteristic line can be defined via  DIP switch DIP4. Here is distinguished between  a linear and a square root extracting output characteristic line. When square root extracting  output characteristic line is selected, the  measuring range setting at DIP switches DIP1

Offset adjustment is done at a potentiometer on the circuit board within  an adjustment range of ± 10 % of the device’s pressure range.

Ex-factory this potentiometer is in center position and is lacquer sealed.

All settings and adjustments that are made before must be done in this configuration.

Offset adjustment is carried out using a tool called “screwdriver 2.5”  (blade with in mm).

Measurement signal filtering

In order to stabilize the pressure measurement signal and the output voltage, the measurement signal is filtered.
The time interval for such averaging can be preset via DIP switch DIP 5 to 1 or 10 seconds.
By a longer filtering interval, the settling time of the sensor is automatically extended.

Offset adjustment is done at a potentiometer on the circuit board within
an adjustment range of ± 10 % of the device’s pressure range.
Ex-factory this potentiometer is in center position and is lacquer sealed.
All settings and adjustments that are made before must be done in this configuration.
Offset adjustment is carried out using a tool called “screwdriver 2.5” (blade with in mm).

Automatic offset setting

1. Before setting the zero point, the device must be in operation
for at least 60 minutes.
2. Connect pressure inputs P (+) and P (–) by means of a hose
(pressure difference between both inputs = 0 Pa).
3. For zero point setting press “key” (auto zero) pushbutton
uninterruptedly for 5 seconds.
A LED signalises prompting the calibration by short flashing,
and after a short countdown the measured (current) offset value is
added to the measurand and zero voltage safe stored.
Correct calibration is confirmed by steady light of the LED for
3 seconds respectively indicated in the display (optional) by switching from “AUTO 0” to “PROG 0”.
Note: By releasing the button during the countdown (counter > 0), zero point setting is immediately terminated!

Manual offset adjustment

At the potentiometer OFFSET ΔP can be balanced.
The adjustment range is ca. ± 10 % of the pressure range.
Here another reference point different from zero point can be used.

Readout in the display

In the 1st line of the display, the ACTUAL pressure up to the measuring range
limit is displayed.
Switching between the units Pa and hPa (100 Pa = 1 hP) happens automatically.
Pa = Pascal
hP = Hektopascal

U – variant
(Range: 0…+ xx Pa)
After successful zero point calibration, the output voltage is 0 V at 0 Pa pressure difference (with the offset knob in central position)!
Output voltage 0…10 V for pressure difference from 0 Pa to final value

I – variant
(Range: 0…+ xx Pa)
After successful zero point calibration, the output current
is 4 mA at 0 Pa pressure difference (with the offset knob
in central position)!
Output current 4…20 mA
for pressure difference from 0 Pa to final value

U – variant
(Range: – xx … + xx Pa)
After successful zero point calibration, the output voltage
is 5 V at 0 Pa pressure difference (with the offset knob in
central position)!
Output voltage 0…10 V
for pressure difference – ΔP … +ΔP

I – variant
(Range: – xx … + xx Pa)
After successful zero point calibration, the output current
is 12 mA at 0 Pa pressure difference (with the offset knob
in central position)!
Output current 4… 20 mA
for pressure difference – ΔP … +ΔP

General notes

This device can be mounted in any position. The voltage output is short- circuit proof. Applying overvoltage at the voltage output will destroy this device.
Pressure ranges are indicated on the device label. Applying measuring pressures beyond that range will cause mismeasurements and increased deviations
or may destroy the device.
– Attention! When leading in cables, make sure, they do not go under the board. This might buckle or damage hose connections!
– The voltage output is short-circuit proof. Applying overvoltage at the voltage output will destroy this device.
– Pressure inputs are “poled“ i.e. the above-atmospheric pressure line must be connected at input P+
and the below-atmospheric pressure line must be connected at input P–.
– At an adjusting element, the output signal can be offset by ± 10 % of the final value of the measuring range.
In this way, possible ageing or drift effects can be compensated.
– Adjustment may only be made at the presence of differential pressure (ca. 90 % of final value).
– By changing the offset at the adjusting element, factory-calibration is lost!
– If this device is operated beyond the specified range, all warranty claims are forfeited.
Our “General Terms and Conditions for Business“ together with the “General Conditions for the Supply of Products and Services of the Electrical and
Electronics Industry“ (ZVEI conditions) including supplementary clause “Extended Retention of Title“ apply as the exclusive terms and conditions.
In addition, the following points are to be observed:
– These instructions must be read before installation and putting in operation and all notes provided therein are to be regarded!
– A suitable weather and sun protection hood must be used when installed outdoors.
– Devices must only be connected to safety extra-low voltage and under dead- voltage condition. To avoid damages and errors at the device (e.g. by voltage
induction) shielded cables are to be used, laying parallel with current- carrying lines is to be avoided, and EMC directives are to be observed.
– This device shall only be used for its intended purpose. Respective safety regulations issued by the VDE, the states, their control authorities, the TÜV and the local energy supply company must be observed. The purchaser has to adhere to the building and safety regulations and has to prevent perils of any kind.
– No warranties or liabilities will be assumed for defects and damages arising from improper use of this device.
– Consequential damages caused by a fault in this device are excluded from warranty or liability.
– These devices must be installed and commissioned by authorized specialists.
– The technical data and connecting conditions of the mounting and operating instructions delivered together with the device are exclusively valid. Deviations from the catalogue representation are not explicitly mentioned and are possible in terms of technical progress and continuous improvement of our products.
– In case of any modifications made by the user, all warranty claims are forfeited.
– This device must not be installed close to heat sources (e.g. radiators) or be exposed to their heat flow.

Direct sun irradiation or heat irradiation by similar sources (powerful lamps, halogen spotlights) must absolutely be avoided.
– Operating this device close to other devices that do not comply with EMC directives may influence functionality.
– This device must not be used for monitoring applications, which serve the purpose of protecting persons against hazards or injury, or as an EMERGENCY STOP switch for systems or machinery, or for any other similar safety-relevant purposes.

– Modifications of these records are not permitted.
– In case of a complaint, only complete devices returned in original packing will be accepted.

Notes on commissioning:
This device was calibrated, adjusted and tested under standardized conditions. When operating under deviating conditions, we recommend performing an
initial manual adjustment on-site during commissioning and subsequently at regular intervals.

Commissioning is mandatory and may only be performed by qualified personnel!
These instructions must be read before installation and commissioning and all notes provided therein are to be regarded!

SUPPLY VOLTAGE :
For operating voltage reverse polarity protection, a one-way rectifier or reverse polarity protection diode is integrated in this device variant.
This internal one-way rectifier also allows operating devices on AC supply voltage.
The output signal is to be tapped by a measuring instrument. Output voltage is measured her against zero potential (O V) of the input voltage!

****When several devices are supplied by one 24 V AC voltage supply, it is to
be ensured that all ”positive“ operating voltage input terminals (+) of the
field devices are connected with each other and all ”negative“ operating
voltage input terminals (–) (= reference potential) are connected together
(in-phase connection of field devices). All outputs of field devices must be
referenced to the same potential!
In case of reversed polarity at one field device, a supply voltage short- circuit would be caused by that device. The consequential short-circuit current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!
