The OMEGA™ HX94B Series temperature/relative humidity transmitter provides a linearized and temperature compensated output signal of 4 to 20 mA, 0 to 1 Vdc, 0 to 5 Vdc or 0 to 10 Vdc depending upon the model selected for both temperature/relative humidity measurement. The output signals have been calibrated and scaled to 0 to 100°C for temperature and 0 to 100% for relative humidity. The digital temperature and relative humidity sensor is protected by a stainless steel cap that is easily removed for cleaning. The NEMA 4 stainless steel enclosure and cable entry connection provides weather tight protection. The stainless steel enclosure terminates to a 6 feet shielded cable. The cable end is either stripped leads or terminates to a 4-pin connector.

Manual says humidity can be calculated using specific equations corresponding to a specific output voltage. What equations should one use if the voltage reading is 1.1 Volts or 0.9 Volts. Also, what should be the operating input voltage for the HX94B?

Asked by: AminB
Hi AminB, The HX94B series includes 3 models with voltage output. HX94BV0, HX94BV1, HX94BV2. Manual provides the correlation between voltage and RH/Temperature levels. Best regards OMEGA

Which model withstand a temperature range from -10C to +85C, also capable to read from zero to 100%RH, water proof. We have been using the model HX71-V1

Asked by: Hilario Barboza
Hi Hillario, Thank you for the inquiry. Unfortunately this series is not designed for condensing humidity environment. We do not offer compatible alternate sensor for wet environments. Best regards OMEGA

The manual states that for a 0-1V output and 0-5V output, the input power supply must be between 9-30 Vdc at 100 mA. These formulas for humidity provide different results. Which formula would be more accurate for a 0.99 V output or 1.1 V output.

Asked by: AminB
Thank you for your inquiry. For a 0.99 V output you will need to use the 0-1 V formula. For a 1.1 V output, you will need to use the 0-5 V formula. If you have any questions, please call 1-888-826-6342, ask for Temperature Engineering and speak to one of our temperature engineers over the phone.
