Humidity, temperature transmitter. Outdoor, indoor use. Bar type.

Relative humidity, temperature sensors at 700mm stem. Measured values are also converted to other humidity interpretations: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.

Programmable temperature and humidity transmitter is equipped with temperature and relative humidity sensors. Measured values are also converted to other humidity interpretations – dew point temperature, absolute humidity, specific humidity, mixing ratio, or specific enthalpy. Degrees Celsius and Fahrenheit are user selectable. Transmitter contains a microprocessor-based control circuitry in a durable plastic case with connection terminals and sensors with a filter with stainless steel mesh. Humidity transmitters is equipped with two galvanic isolated 4-20mA outputs. Configuration of outputs and output range are user adjustable. Large dual line LCD for simultaneous display of T+RH or other humidity interpretation is an advantage. Display is possible to switch off. Computerized design ensures temperature compensation of the humidity sensor and fails indication. State-of-the-art capacitive polymer sensor ensures excellent calibration long-term stability, inertia against water, and condensation. Transmitters are designed for use in non-aggressive environment.

Applications – Measuring and control of air humidity at:

• Building HVAC management
• Building HVAC automation
• Warehouses
• Glasshouses
• Manufacturers
• Museums, archives, galleries
• Air-conditioned rooms
• Weather stations

Outputs are set to maximum range from the manufacturer (-30 to +125°C, 0 to 100%RH). To set other range by the user buying of SP003 cable is necessary – see Optional accessory. Free configuration program TSensor for transmitter adjustment is ready to download anytime. If different adjustment of outputs is required, please specify required output values (RH, T, Tdp, ..) and required ranges in the order. Adjustment is free of charge. Any measured value – temperature, relative humidity, dew point temperature, absolute humidity, specific humidity, mixing ratio, or specific enthalpy can be assigned to each output of the transmitter. Also, identical values can be assigned to both outputs.

Typical application wiring of dual output transmitter

Ordering Example: Transmitter T3117, output 1: RH 10 to 90%, output 2: temperature 0 to 35°C
