The electronic PREMASREG® 716x pressure sensor and switch is equipped with measuring functions for volume flow, differential pressure, filter monitoring and liquid level detection based on pressure measurement in clean air. The devices with a housing made from impact-resistant plastic, with cable gland or M12 connector according to DIN EN 61076-2-101 and with metal pressure port nozzles (quick connect optional) are fitted with one switching output, one continuous output and one backlit display for setting the switching point and displaying the ACTUAL values. The piezo resistive measuring element guarantees a high degree of reliability and accuracy.

This pressure sensor is used in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, in large-scale catering facilities, for filter monitoring and level measurement or for triggering frequency converters. The medium measured is air (non- precipitating), or other gaseous, non-aggressive, non-combustible media.
It has a manual zero point pushbutton and an offset potentiometer for final value correction. Parameter entry is menu-based and is easy to perform using three buttons with the help of the display. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible. A connection set ASD-06 (2 m connection hose, two pressure nipples, screws) is included in the scope of supply.

Setting the offset:

Automatic offset correction:

  1. The device must be operative for at least 60 minutes before zero point setting is started.
  2. Connect pressure inputs P (+) and P (­) with a hose. (differential pressure between the connections = 0 Pa).
  3. To set the zero point, press the AUTO ZERO pushbutton for 10 seconds without interruption.

By pressing the pushbutton, a countdown of approx. 10 seconds is started. The yellow LED is flashing and the countdown is shown on the display. After the countdown period has elapsed, zero point calibration takes place. This is indicated by continuous light of the LED, and on the display by switching from “AUTO 0” to “PROG 0”. Note: When releasing the pushbutton during countdown (counter > 0), zero point setting is immediately aborted!

Manual offset adjustment:
The offset potentiometer functions in addition to and independently of the automatic setting of the zero point. With the OFFSET potentiometer, a deviation outside of the zero point can be aligned. The range for adjustment is approx. ± 10 % of the pressure range.

Automatic zero point calibration (optional):
A zero point calibration is carried out cyclically via an internal valve. The cycle time can be set between 15 minutes and 24 hours using the SET potentiometer. During the automatic calibration, the output value remains at its last pressure value.

Configuring the measuring function:

Setting the function type
Press the SELECT pushbutton to activate setup mode. Use the two UP and DOWN pushbuttons to select the desired function type (formulas for the function types, see page 11).

Complete the entry by pressing the SELECT pushbutton. After selecting the measuring function, you are automatically guided through the parameters that must be set (see next page).

Setting the parameters:
Type 0: Volume flow rate

K factor from 1 to 3000
Depending on the manufacturer, the K factors are calculated differently. Therefore, it is necessary to use the corresponding calculation formula to enter data:

Unit of volume flow rate

0 = m3/s
3 = liters/s
1 = m3/min
4 = liters/min
2 = m3/h
5 = liters/h
kS+S = kEBM-PAPST
kS+S = k ZIEHL-ABBEG
kS+S = kGEBHARDT / 0.7746
kS+S = kROSENBERG / 0.7746
kS+S = 3600 / k FLÄKT

Volume flow rate at max. output signal 10 V
Setting (measuring range end value = 10 V) 10 % to 100 % of the max. possible volume flow rate in the selected measurement unit.

Relay switching threshold at volume flow rate
Setting (relay switch point) 10 % to measuring range end value in the selected measurement unit.

Type 1:
Differential pressure

Differential pressure for max. output signal 10 V Setting (measuring range end value = 10 V) 10 % to 100 % of the max. possible differential pressure in Pa.

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!
– 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.
– 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.

Notes on commissioning: This device was calibrated, adjusted and tested under standardised 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 0 – 10 V 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 this device is operated on DC supply voltage, the operating voltage input UB+ is to be used for 15…36 V DC supply and UB ­ or GND for ground wire!

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!
