Relative Humidity & Temperature Transmitters

The HF5-EX series can only be used together with the intrinsically safe HC2-EX probes to provide a temperature and humidity monitoring system suitable for use in a Zone 1 or 2 Hazardous Area. The relative humidity and temperature can be displayed and output as analogue 4-20mA signals. Calculated psychrometric values such as dew point or mixing ratio can also be derived and provided as one of the output signals. Probes are interchangeable and suitable for mounting in Zone 0/20. Ranges: Temperature -40 to +60C, Relative Humidity 0 to 100%. Accuracy 0.8%RH, 0.1C.

Hazardous Area Approved

The new Hygroflex 5 Series offers the ultimate in performance and flexibility due to its interchangeable hygroclip 2 probes. The HF5 series offers a unique calibration and adjustment process and the ability to interchange probes in just a few seconds. System accuracy is 0.8% RH and 0.1 K. The transmitters come in various configurations and the optional software allows digital versions to be networked together to form a dedicated environmental monitoring system.

The new Hygroflex 3 Series is the latest development in HVAC transmitters for relative humidity, temperature and dew point. The HF3 series offers you maximum reproducibility and a guaranteed system accuracy of <2% RH and 0.3 K. The transmitter has 2 or 2x2 wire 4 - 20mA loop outputs or 3 wire 4-20mA/0-10V outputs (User scaleable with software). The transmitters come in various configurations and the optional HW4 Software allows many useful functions to be activated.

The RH-W Wall Mounted Humidity and Temperature Sensors offer the latest technology high precision and accuracy Relative Humidity & Temperature elements. Jumper selectable 0-10v (0-5V) and 4-20mA (2/3-Wire) outputs. An optional multi-line backlit LCD display is available, custom temperature ranges can be requested between -20 and +50°C and direct PTC/NTC sensing Elements. Enthalpy and Dew Point Measurements optional.

The RHT-WM-485-LCD and RHT-DM-485-LCD transmitters include high precision and stability sensors for measuring relative humidity and temperature. They are microprocessor based devices and, therefore, allow being entirely configured through an RS485 interface using the Modbus RTU command. The DigiConfig software allows the configuration of all transmitter features as well as its diagnostic procedure.The RHT-WM-485-LCD model is intended for wall mounting while the RHT-DM-485-LCD model is equipped with an elongated sensor rod for installation in ducts or through walls.

The RHT Climate transmitter has an integrated temperature and relative humidity sensor on the wall mounted housing, or at the end of a duct mounted probe. The Stainless Steel probe is available in 150, 250 and 400mm length probes. All RHT Climate transmitters are available with 2 analogue outputs configurable by the NXperience software with options for 4-20mA or 0-10V outputs. Unit with the backlit LCD display can also be configured using the buttons on the unit. A Modbus option with additional psychrometric data is available for networking units via an RS485 connection and can also be collected via a USB connection for configuration. The RHT Climate is more precise, versatile and provides more psychrometric information than the other RHT transmitters.

Relative Humidity and Temperature Transmitters RHT-WM and RHT-DM with 4-20mA or 0-10vDC outputs for temperature and humidity Wall or duct mounting - insertion lengths 150 or 250mm. Using the digital communication interface, the transmitter parameters can be configured to tailor a particular application. The RHT-WM model is intended for wall mounting. The RHT-DM comes with a probe tip for duct mounting. Available with programmable ranges from -40 to +120°C (Wall-mounted units, -10 to 65°C) and 0-100% RH. Electronics module limited to -10 to 65°C
