Are these designed to be installed in a bulkhead or throughpanel configuration? If so what is the recommended method for accomplishing this?

Asked by: TimMcMan
Hi TimMcMan, Thank you for the inquiry. The HX302C is designed for mounting on a wall. Manual supplies detail including mounting hole location. Best regards OMEGA

Is there a more extensive manual for the HX303AV model?  This a jumper on it to change the output range to 0 to 5V but that is not mentioned in the online manual.  I'm seeing 0.4V for ambient temp reading and 0.9V for RH.  Seems wrong?

Asked by: Spacepope
Thank you for the inquiry. Manual for the HX303A; https://assets.omega.com/manuals/M5072.pdf. For more trouble shooting assistance please forward email to TEMP@OMEGA.COM. Best regards OMEGA

the data that I am getting to my PLC is not coming through as a percentage but rather a 4 digit number. Is there a formula that I need to apply to the data to get the information that I need? I doubt 2894 is the correct RH. Any help is greatly appreciated

Asked by: James667
Hi James, You'll need to check the PLC scaling and adjust as needed. The 4 to 20 mA outputs of the HX303AC are scaled to represent 0 to 100 % RH and 0 to 100 C. Best regards OMEGA
