The HX93B and HX93BD Series transmitters provide remote and on-site monitoring of temperature and relative humidity. Both series output a linearized current or voltage signal proportional to the temperature and relative humidity. Relative humidity output is temperature compensated. Current output models enable placing of the transmitter at a remote location virtually any distance away from the measuring device. The HX93BD models feature a built-in digital display that indicates both temperature and relative humidity simultaneously. All models use an accurate digital sensor. A stainless steel mesh type filter, easily removable for cleaning, protects the sensor. Mounting screws are easily accessible inside the rugged, polycarbonate enclosure which protects the electronics to NEMA 13 (IP54) specifications.

Rated 5 out of 5 by from Temperature/Relative Humidity Transmitter Tried other units first, with inconstant and sporadic readings. This unit is very consistent and accurate.

Rated 5 out of 5 by from Works great even in a dirty environment I got several of these units for capturing ambient temperature and humidity around some of the batch mixers in my plant. The units were easy to set up and were quite reliable, especially considering the dirty environment that they lived in.

Rated 3 out of 5 by from Generally very good. Although they are expensive it is nice to have both the display and the analog output. They are generally reliable for extended periods of time.However, one of the last two I purchased was dead out of the box. That was not something I had seen before, having used dozens of this generation and the previous generation.

Rated 1 out of 5 by from Unknown functionality due to manufacturing issue I bought this sensor and it was labeled properly HX93BV2 for the 0-10Vdc version on the outside but on the inside, the printed circuit board is marked as "C" indicating it's a 4-20mA version. So I exchanged it and alas, the second one has the same assembly issue.

I have a hx93bd the led just shows hash marks, no temp or RH

Asked by: Rob111
Possible sensor issue. My not be fully seated or plugged in. Best to call in and discuss.

I have an HX93BDC that I bought some time ago to have as a spare for one in service. I powered it up today and the analog outputs are working properly but there is no display. The backlight works, but no readout of temperature or humidity.

Asked by: Mike01
Hi Mike01 Thank you for the inquiry. Please check connections to the display board. For further assistance please forward request to TEMP@OMEGA.COM. Best regards OMEGA

Is the chassis ground terminal, #5, for safety grounding only, or does connecting this affect the performance of the device?

Asked by: CharlieP
Hi CharlieP Thank you for the inquiry. 5 and 4 terminals are internally connected. These are used as common (-) return side of power source. This is not a safety ground connection. Best regards OMEGA

Can we calibrate the HX93BC? If so how would we do this, if not can we send it back to you for calibration? What would you recommend?

Asked by: wjwhite
Hi wjwhite, Thank you for the inquiry. HX93BC needs to be returned to Omega for calibration service. Best regards, OMEGA

This sensor can be used to measure RH and temperature in a biogas stream with % CH4: 50-60 % CO2: 30-4 % O2: 1-2 ppm H2S: 1000-3000 ppm Temperature: 30-50 ° C Pressure: 1-1.

Asked by: jimontoy
Hi JLMontoy Thank you for the inquiry. This sensor would not be compatible with the detailed process gas combination. These are calibrated in an standard air environment. Best regards OMEGA

Does the HX93BDC have calibration certificate available from Omega? We are using it only for personal comfort in a lab but wanted to see if we should calibrate it prior to installation or if it is factory calibrated and meets accuracy specs as received.

Asked by: Doug88
Hi Doug88, Thank you for the inquiry. The HX93BDC units are calibrated to factory specs.They do not require extra calibration before service. Certificate of conformance is included with your order. Best regard OMEGA
