sensor

The TRTN temperature transmitters are intended for room mounting in HVAC systems. The temperature sensor gives output signal 0...10 V DC or 4...20 mA via the built-in electronics.

Supply voltage
For output signal 0...10 V, the transmitter should be supplied with 15...40 V DC or 24 V AC ±20%. For output signal 4...

Function
Transmitters intended for wall mounting in HVAC systems. The sensor is mounted in the cover-part of the casing. The cover is easy to detach from the back by means of snap-in grips and detachable terminals. This makes mounting easier. Furthermore, no cables have to be disconnected, simplifying service and replacement.

The temperature transmitters have an element which gives a signal that is proportional to the temperature. The measuring signal is converted by the built-in electronics to output signal,0...10 V or 4...20 mA.

Temperature sensors intended for measuring surface temperature. The sensors have PT100- or PT1000- element. Modern sensors in the Tempero-series that have an unobtrusive design. TG-AH/PT100 and TG-AH/PT1000 are intended for clamp-on mounting. Clamp and heat conductive contact paste are included.

The transmitter consists of a stainless steel sensor hausing and a ceramic membrane. Resistors are applied to the membrane by means of thick-film technology.
Pressure affecting the membrane gives a change in resistance depending on the flexing of the membrane. The resistance value is transferred to a proportional
output signal by means of the built-in electronics.

Function
The transmitter consists of a plastic sensor housing and a membrane of silicone LSR. The differential pressure affects the membrane which is connected to the sensor element. The element is manufactured with state-of-the-art technology and has a ceramic beam onto which thick-film resistors have been applied.

The transmitter consists of a sensor hausing in stainless steel and a ceramic membrane. Resistors are applied to the membrane in thick film technology. The pressure affecting the membrane results in a change of resistance value depending on the bending of the membrane and this is transferred by means of the built-in electronics to a proportional output signal.

Application
The differential pressure transmitter is used in building automation to monitor pressure in air and other noncorrosive gases. Three different models are available for an optimal adaptation to the application. All models are equipped with a LED display which makes it easy to read out the pressure value.

The differential pressure transmitter DMD is based on microprocessor technology and it has a logical menu system. Settings of working range, damping, and zero-point adjustment are made using buttons under the lid.

Measuring technique
Pressure measurments are obtained by means of a sensor that uses a ceramic measuring beam.
