CO2-transmitters for room mounting

RC-CO2RT
Enquire

CO2RT… is a series of room transmitters for measuring carbon dioxide levels in air. The units have a built-in temperature sensor with output signal 0…10 V DC and PT1000-sensor.

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 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, which simplifies service and replacement.

  • CO²-level 0…2000 ppm
  • Temperature 0…50°C
  • Relative humidity 10…90% RH (CO2HRT)
  • With or without LCD display
  • Excellent long term stability
  • Snap-in cover
MWA Code Range CO² Accuracy Temp. Range Hum. Range Class
RC-CO2RT 0…2000ppm < ± (50 ppm + 2 % of value) (25 °C) 0…50°C 10…90% RH IP30

Combined humidity/temperature transmitter for duct mounting

RC-HTDT2500(-420)
Enquire

Transmitter for measuring temperature and relative humidity.

HTDT2500(-420) 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.

Filter : The transmitter sensor element is protected by a membrane filter. This can be changed to a sintered brass filter, which is recommended if operating in an environment with a high degree of pollution.

  • Output signal 0…10 V DC or 4…20 mA, as well as passive PT1000
  • Supply voltage 24 V AC or 15…35 V DC
  • Protection class IP65
  • High accuracy
  • Short reaction time
  • Long-term stability
MWA Code Output Temp. Accuracy Class Hum. Accuracy
RC-HTDT2500(-420) 4…20 mA ±0.3 K at 20°C IP65 ±2.5 % at 20°C

Humidity/temperature transmitter for room mounting

RC-HTRTN-420
Enquire

Room transmitters for measurement of humidity and temperature.

The HRTN humidity and temperature transmitters are intended for room mounting in HVAC systems.
Relative humidity : The transmitters have 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 an output signal 0…10 V or 4…20 mA.  The sensor element has rapid response to changes in humidity and excellent long-term stability.  The element also has good durability in contaminated environments.
Temperature : HTRTN, HTRTN-D and HTRTN-420 also have a temperature sensor, which gives an output signal 0…10 V DC or 4…20 mA via the built-in electronics.

  • Output signal 0…10 V DC or 4…20 mA
  • Protection class IP30
  • Good long term stability
  • Snap-on cover
  • Option with display
  • Resistant to contamination
  • Accuracy ±2% RH (40…60% RH), ±3% RH (10…90% RH)
MWA Code Output Temp. Range Accuracy Class
RC-HTRTN-420 0…10 V DC | 4…20 mA 0…+50°C ±3 % RH (±2 % at 40…60 % RH) IP30
