Transmetteur de température et d'humidité
A combined wall or duct transmitter that delivers matched temperature and relative-humidity signals from one serviceable sensing assembly.
- Combined T and RH Measurement
- Matched Dual Outputs
- Replaceable Probe Filter
- Local Display Option
Introduction de produit
The temperature and humidity transmitter places a stable temperature element and capacitive humidity sensor in the same aspirated probe so both variables represent the same air sample. Internal electronics compensate and linearize the measurements, then provide separate analog signals or a digital network value set. A replaceable filter protects the probe, while an optional display shows temperature, relative humidity and derived dew point locally. Wall, duct and remote-probe configurations address different cleanroom and AHU measurement locations.
Key Features
Separate calibrated outputs simplify connection to environmental monitoring and HVAC controls.
Replaceable probe filters protect the sensing assembly without replacing the transmitter body.
Optional display presents temperature, RH and derived dew point at the installation location.
Préoccupations du client produit
Temperature and humidity values become difficult to interpret when they come from different locations, response times or sensor housings.
Separate sensors report conditions from slightly different air zones.A combined probe measures both variables from one shared air sample.
Humidity drift cannot be distinguished from temperature-driven RH change.Synchronized temperature and RH trends reveal whether moisture content or temperature caused the shift.
Probe contamination requires replacement of the entire transmitter.A serviceable filter and replaceable probe option reduce maintenance scope.
Commissioning staff cannot verify the local reading without a laptop.An optional display provides immediate temperature, humidity and dew-point values.
