EC 36 Transmitter
SAM Smart Area Monitor
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.
- Integrated alarm control
- 3 alarm relays
- AutoCal for easy and fast calibration
- Illuminated 4-digit LCD display for easy reading
- Extremely rugged casing
- Remote control and remote display – even for Ex endangered areas
- Smart Sensor Technology
ZD 21 Transmitter
Low cost long-term solution
Particular long sensor life makes the ZD21 a low
cost transmitter for oxygen monitoring. The
expected lifetime for the sensor is 5 years in
continuous operation. A robust aluminium casing
protects the sensor and the circuitry from impacts,
splash water and dirt.
The ZD21 is an "intelligent" transmitter. The
comprehensive electronic allows for easy
operation and maintenance and also increases
the operational safety and accuracy. In less
than 2 seconds the ZD21 responds to
changing oxygen levels. This extremely short
response time allows to take measures in time
to prevent considerable damage.

- Extremely fast response time: t90< 2 sec.
- No influences from pressure, humidity or temperature
- No damage from CO2
- Maintenance free, service check every year
- Different detection ranges available
Transmitter ZD22
for oxygen (O2)
The Transmitter ZD22 is specifically designed for long-term monitoring of oxygen concentrations.

The integrated thermostatic control of the sensor element achieves accurate measuring results in the entire temperature range, regardless of the operating temperature. The sensor selectively detects the oxygen and is sensitive to many sensor poisons known at the electrochemical sensors. It can be also permanently used in environment with high concentrations of CO2 or in dry atmosphere. A special equipment is available to protect the transmitter when used in very difficult.
