Regin sensors and switches – Comfortable and economic indoor climate

To measure is to know.Temperature, carbon dioxide, air circulation and humidity in buildings are constantly affected by conditions outside and inside the building. To maintain a pleasant indoor climate and safeguard energy-efficient operations the control systems need constant information.

Regin offers a comprehensive programme of sensors and switches for every need. Our products are well known for high quality, accuracy and long term stability.

You can really trust in them.

The temperature transmitters and sen-sors with housing in the Tempero series are designed according to “Ready-Steady-Go” with the aim of simplifying installation, and commissioning.

The Regin room transmitter is available as a combined CO2, temperature

and humidity transmitter.

The Regin differential pressure transmitter for air has four selectable measuring ranges.

in the same unit. The LCD display gives a good overview of measured values


The Regin range includes NTC, PT100 and PT1000 temperature sensors and transmitters. For room, pipe, duct, im-mersion and floor mounting etc.

High concentrations of CO2 cause headaches, dizziness and fatigue. The maximum limit of 1 000 ppm should therefore not be exceeded. Regin’s CO2 transmitters give a direct indication of the indoor air quality, which makes it possible to increase the supply air as long as necessary.

A clogged filter impairs quality of the supply air and is bad economy. Regin’s differential pressure transmitters control the condition of filters and give an alarm when service is needed.

The relative humidity (RH) in buildings is recommended to be between 25-80% in the winter and 20-70% in the sum-mer. At any season of the year, you can rely on Regin’s humidity transmitters and humidistats.

The HDT series – Duct humidity/temperature transmitters

HumidityHumidity transmittersRegin humidity transmitters have a capacitive thin-film element that gives a signal that is proportional to the relative humidity (RH). The measuring element rapidly responds to changes in humidity and can be subjected to up to 100% RH without being damaged.

HumidistatsRegin humidistat are used for controlling humidifying and/or dehumidifying in HVAC systems. The humidi-stats have human hair or a synthetic element as sensor medium. The hair stretches as the humidity increases and shrinks as the humidity decreases. The changes are transmitted to a micro switch.

Pressure and Air flowDifferential pressure switchThe differential pressure switch has a synthetic spring suspended membrane which is linked to a changeover contact. When the differential pressure exceeds the setpoint value the contact switches. The differential pressure switch is used to supervise and monitor fans, filters and air handling units, to control defrosting func-tions etc.

Pressure transmittersRegin pressure and differential pressure transmitters use a ceramic measuring beam. The differential pressure affects a membrane that works directly against the measuring beam with a film resistor. When the resistance changes it is converted to a proportional output control signal.

High degree of accuracy•

Few moving parts – rapid response•

Excellent long-term stability.•

Duct sensor for air velocityThe air velocity sensor operates with a specially designed thin-film element which is heat sensitive (the hot-film anemometer principle). The cooling rate of the element, which depends on the air velocity, is measured and trans-formed to an output signal proportional to the air speed.

Stable output signal compensated •for varying temperature

Extremely high frequency response•

Not sensitive to contamination by dust etc. •

Flow switchesThe flow switch operated by an electrical blade-type tripping device interrupts the electric control circuit when there is insufficient water circulation owing to abnormal conditions.
