CI 21 Transmitter
Low Maintenance Ammonia Detection
The charge carrier injection (CI 21) sensor is a progressive
development to improve upon current ammonia refrigeration
detection methods. With CI 21 technology sensor life is no longer
limited to ammonia exposure levels. This reduces replacement
costs associated with electrochemical sensors.
Charge carrier injection technology also eliminates false alarms
frequently associated with metal oxide sensing (MOS). These,
along with other features, provide reliable, cost effective, longterm
safety.
The CI 21 transmitter is an advanced development to which all
other ammonia transmitters will be compared.
- Stable long-life charge-carrierinjection sensor
- Sensor is unaffected by exposure to high gas concentrations
- Low temperature operation to -40oF
- Low cross-sensitivity
- Eliminates costly false alarms
- Low cost of ownership
Transmitter IR 24
Stationary monitoring of carbon dioxide (CO2)
The IR 24 does not contain any moving parts,
which may be subject to wear and tear. This
ensures a long lifetime and low maintenance
cost. Additional safety is provided by the permanent
self-check and function test of the
GMA controller. Sensor and electronics are
protected in a solid enclosure from dust and
water according to IP 54. This ensures that
water cannot enter the detector, even in wet
environments.
Behind a service lid on the front of the IR 24
you find potentiometers and test connectors
for easy adjustment of zero point and span.
This allows one-man calibration on-site and
reduces service down-time.
- Selective NDIR detection principle
- Long sensor life for low follow-up cost
- Easy handling
- Signal output either 0.2 .. 1 mA or 4 .. 20mA
- Potentiometers for easy adjustment of zero point and span

CS 21 Transmitter
Low Cost Solid State Sensor
The CS 21 transmitter uses the proven chemosorption detection principle for detection of toxic gases, vapors and combustibles. The rapid response of the transmitter provides opportunity to take counter measures and thereby limit damages. The long life of the sensors makes the CS 21 a low-cost solution for your detection needs. A transmitter can be continuously operated for more than 5 years
- High sensitivity to a broad range of refrigerants
- Long sensor life
- Fast response
EC 36 Transmitter
SAM Smart Area Monitor EC 36 - Stand alone
The EC 36 is a stand-alone transmitter. In every EC 36
there is a sensor, control electronic and relays for
triggering of alarms. LEDs in the front panel immediately
indicate the alarm. The signal output is provided as a 4..20
mA signal.
The EC 36 is the most enhanced single point gas detector
available offering features never known to the industry.
Equipped with AutoCal, the EC 36 can be comfortably
calibrated in a matter of seconds. A 17 mm high backlight
LCD-display indicates the gas concentration, status report
and, if operated in service mode, all settings. In
applications where the display of the EC 36 cannot be read
because of its mounting position, a remote display is easily
connected to an interface. Using the remote control, nonintrusive
remote calibration can be performed, making
forklifts or ladders a thing of the past.
