ZILA ZMF-200e-IR CO2 Sensor

ZILA ZMF-200e-IR CO2 Sensor

Scope of Delivery

CO2 Sensor ZMF-200e-IR
Mounting- and operating instructions

Product description

The ZMF-200e-IR is a carbon dioxide CO2 sensor, designed solely for measuring the carbon dioxide concentration in the ambient air, under the operating conditions mentioned below. The device is available in different measuring ranges and has an internal error monitoring. The measurement of the carbon dioxide CO2 concentration takes place via the optical measuring principle NDIR (nondispersive infrared absorption measurement). With the integrated 4…20mA output signal, the measurement signals can be evaluated by a downstream device.

The sensor unit is located in a stainless steel housing and is mounted on a diffusion opening. The cable entry is realized via cable glands. The device is powered via 12…24 V DC and can be mounted on the wall.

Product features

Measurement principle

The CO2 sensor ZMF-200e-IR measures the absolute CO2 concentration in the ambient air quickly and accurately with a dual-beam infrared photometer (NDIR). The measuring range is linear.

Measurement ranges

The sensor measures the CO2 concentration in the ambient air in the range of 0…5000ppm. Other measuring ranges up 100vol% are available on request:

0… 2.000 ppm 0,2 vol %
0… 5.000 ppm 0,5 vol %
0… 10.000 ppm 1,0 vol %
0… 20.000 ppm 2,0 vol %
0… 50.000 ppm 5,0 vol %
0… 200.000 ppm 20,0 vol %
0… 1.000.000 ppm 100,0 vol %

Functions

usable as a CO2 sensor with 4…20mA signal output

General instructions

CAUTION: Poisoning with carbon dioxide (CO2) is life threatening!

CAUTION: Under certain circumstances, the CO2 sensor ZMF-200e-IR cannot measure the CO2 concentration in the ambient air (power failure). Users and operators of plants are in charge of personnel safety and security according to applicable laws.

Read the instructions carefully
Keep the instructions
Mounting, commissioning and electrical connection allowed for experts only
Repairing is only allowed for experts only
The mentioned international protection marking is only guaranteed when the device is built-in correctly and the electrical cables are proper connected
Only operate the device with the correct power supply
Modification of the device is forbidden and releases the ZILA GmbH of any guarantee and liability

Mounting and Commissioning

Mounting

The ZMF-200e-IR has to be mounted on a solid, flat and dry wall. The ambient conditions must be adhered.

When mounting outside, a protection against direct weather influences is necessary.

The device must be installed protected against splash water and condensate.

Carbon dioxide CO2 is heavier than air and sinks to the ground. When using the ZMF-200e-IR for personal protection, mounting at ground level is recommended.

Electrical connection

Cable connection

White V+ (12…24 V)
Brown Green
GND Output (4…20 mA)

Commissioning

Since the CO2 sensor ZMF-200e-IR is a sensitive measuring device, an appropriately cautious handling of the device is recommended.

Ensure prior to installation and commissioning, that the environmental conditions are suitable for the use of the device.

Make sure that the CO2 sensor is connected correctly and that the power supply is switched on.

Calibration

A calibration of the device is not necessary with standard applications. An expert may perform a calibration if required. In SIL2 applications we recommend annual calibration of the sensor with a certified test gas.
