1 Sensors and switches Temperature, Pressure, Humidity, Air flow, CO 2, CO and NO 2

2 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 energyefficient 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. 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 You can really rely on them. The Regin room transmitter is available as a combined CO 2, temperature and humidity transmitter. The temperature transmitters and sensors with in the Tempero series are designed according to Ready- Steady-Go with the aim of simplifying installation, and commissioning.

3 The Regin range includes NTC, PT100 and PT1000 temperature sensors and transmitters. For room, pipe, duct, immersion and floor mounting etc. High concentrations of CO 2 cause headaches, dizziness and fatigue. The maximum limit of ppm should therefore not be exceeded. Regin s CO 2 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 summer. At any season of the year, you can rely on Regin s humidity transmitters and humidistats.

4 Humidity Humidity transmitters Regin 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. High accuracy and rapid response Good long-term stability Resistant to contamination Supply voltage: 24 V AC or V DC Automatic adaption to the connected voltages Room, wall or duct mounting Available as single humidity transmitters or as combined humidity and temperature transmitter Humidistats Regin humidistat are used for controlling humidifying and/or dehumidifying in HVAC systems. The humidistats 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.

5 Pressure and Air flow Differential pressure switch The 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 functions etc. Pressure transmitters Regin 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 velocity The 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 transformed 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 switches The 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.

7 CO 2 The Regin CO 2 -transmitters give direct information about the concentration of CO 2 in the room or building. Based on these values the ventilation system is constantly controlled to provide an optimum concentration of CO 2 in the air. Very high accuracy due to patented auto-calibration function with infrared light measuring and reference measuring system Low risk for contamination Short response time High long-term stability Long calibration interval - more than 5 years and no calibration necessary at installation. Standard version: temperature transmitter for room or duct mounting.
