The HX94 relative humidity/ temperature transmitter provides a reliable and low cost method for duct mount monitoring applications. Solid state sensors provide excellent sensitivity, fast response, and stability. Simple hookup and linearized output permit interfacing with most display and control devices. The NEMA 4 stainless steel enclosure and cable entry connection provides weather tight protection. The digital temperature and relative humidity sensor is protected by a stainless steel cap that is easily removed for cleaning.

What is the maximum pressure at which this item can operate?

Asked by: engtech3
Thank you for your inquiry engtech3. Unfortunately, the HX94C is not pressure rated.

Is the HX94C CE compliant?

Asked by: JC2389
The HX94C is not CE approved. The similar HX94BC is CE approved; https://www.omega.com/en-us/control-monitoring/air-soil-liquid-and-gas/temperature-and-humidity-transmitters/hx94b-srs-temp-rh-sig-cond/p/HX94BC Best regards OMEGA

Do we need to purchase a power cable along with DPPT series?

Asked by: shibo_f
Hi Shibo_F, Thank you for the inquiry. Yes, you will need power/signal cable. 4 conductor twisted shielded cable, TX4-100, can be used for this purpose. Best regards, OMEGA

How is the accuracy if the probe has condensation on it? Is there an IP rating for the probe?

Asked by: Eddie J
Hi Eddie Thank you for the inquiry. This probe is not designed to handle condensing humidity conditions. If the sensor gets water droplets on the element it will go into saturation with max output. It would have to dry clean without corrosion to come back on line in calibration. The housing is rated NEMA 4. Best regards OMEGA

Which meter do you recommend to use with this directly to display the value?

Asked by: david_cam
Thank you for your inquiry. You can use our DPPT-series Platinum series universal input meter with this sensor. Here is the link to the pdf catalog: https://assets.omega.com/spec/DPPT-Series.pdf

Can I get the readings with the combination of followings? 1 HX94V + DPPT series Do I need to calibrate DPPT?

Asked by: shibo_f
Hi Shibo_F, The HX94V has 2 outputs so you would need 2 displays. You would need to set up and scale the display to match the calibrated range of the HX94V. Best regards, OMEGA

What are the accessories that are required for this one? To what instrument is the 4 pin connector connected?

Asked by: dan123_dan
Thank you for your inquiry. The primary accessories required are a power supply (shown under accessories) on product page, and 4 conductor cable to mate with supplied connector that would be then connected to an instrument to read the values. There are two 4-20 mA outputs (one for temperature, one for relative humidity) that can be connected to any instrument (panel meter, chart recorder, controller, etc.) that accepts a 4-20 mA signal and can be scaled to represent temperature or relative humidity.
