Building automation system

DTV-X is a pressure switch for supervision of air or non-aggresive, non-flammable gases in air handling system.

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 plastic sensor-housing and a membrane of silicon LSR. The differential pressure affects the membrane which is connected to the sensor element. The element is manufactured with state-of-the art technology with 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.

Function
Transmitters intended for wall mounting in HVAC systems. Temperature sensors The unit has a built-in temperature sensor, working range 0...50°C.

Relative humidity
The transmitters have a capacitive thin-film element that provides a signal proportional to the relative humidity.

HTDT2500 has a capacitive thin-film element that provides a signal propotional to the relative humidity. The transmitter has a high degree of accuracy. The
measuring element responds quickly to changes in humidity. The transmitter has excellent long-term stabilty and a low hysteresis. It can withstand up to 100 % RH (condensing) without accuracy being affected.

HRT250 humidity transmitter is intended for wall/ room-mounting in HVAC-applications, swimming baths, greenhouses,stables etc. The humidity transmitter has a capacitive thin-film element which gives a signal that is proportional to the relative humidity.

The HDT3200 humidity transmitter is intended for duct-mounting in HVAC systems. The humidity transmitter has a capacitive thin-film element which gives a signal that is proportional to the relative humidity. The measuring signal is converted by the built-in electronics to output signal, 0...10 V or 4...

The humidistat uses a synthetic element as sensor medium. The synthetic element stretches as the humidity increases and shrinks as the humidity decreases. These changes are transmitted to a microswitch. The setpoint knob affects the position of the microswitch in relation to the synthetic element. The setpoint can be set at between 35...95% RH.

The humidistat uses human hair as the sensor medium. The hair stretches as the humidity increases and shrinks as the humidity decreases. These changes are
transmitted to a micro switch (two switches). The setpoint switch affects the position of the micro switches in relation to the hair element. The setpoint can be set at between 10% and 95% RH.

The humidistat utilises human hair as its sensor medium. The hair stretches as the humidity increases and shrinks as the humidity decreases. These changes
are then transmitted to a micro switch (or, optionally, to two switches). In case of the HPH, the changes are transmitted to a pin on a potentiometer.

HD1-24/D is an electronic humidistat which converts an input signal 0...10V from a connected humidity transmitter to changeover contact function. When the input signal reaches the setpoint the relay changes over. The electronic humidistat is used to control humidifying and dehumidifying installations.

The detector comes in two different types: one optical (SDD-OE...) and one ionisation (SDD-S65...). Both types are available with or without relay. They are intended for use together with Regin’s ABV... series of control units. The RAC models have a relay and are not to be connected to Regin’s control units ABV...

DCO-S3 is specially designed for enclosed and/or semienclosed car park ventilation applications. It can be used both to control the ventilation system and/or be a part of an alarm system. It is well known that all automobile engines generate CO and that we shall be protected against this toxic gas.

Transmitters with automatic calibration combining measurement of CO2 level and temperature in the same casing. The sensors are 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.

CTDT2 has a probe in the shape of a so-called venturi tube with two air channels. The CO2 sensor element is mounted in the cover part of the casing and the
temperature sensor element is located inside the probe. The air in the ventilation duct is transported to the CO2 sensor element through one half of the probe and then back to the duct through the other half.

COF is a detector intended for demand-controlled ventilation in parking garages and road tunnels etc. The detector is installed for both safety and energy-saving reasons. It measures the carbon monoxide concentration using an electrochemical method of measurement characterised by high selectivity even in low concentrations.

Regin’s CO2RT series with patented auto calibration process sets new standards in CO2 measuring for HVAC applications. In the same casing, the CO2RT series combines measuring of CO2-level, temperature and optional relative humidity. 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.
