Not even close
I've installed one of these so far. It read 84 F. I checked it with two accurate (expensive) and they both read 71 F. Apparently I need to calibrate it.
I hope the rest are a little closer.

Troublesome Product
Constantly read high. Was told by customer support that the unit could handle 18 volts DC maximum despite the fact that the documentation said 24. Changed to a 15 volt supply and still had the same problem. Used a heat gun on the unit and noticed the board had a 90° hot spot on it. Maybe the RTD was picking some of that up. In the end I went with something else.

We have a unit that is consistently reading low by more than 10 degrees. Is there a way to calibrate the sensor?
Thank you for connecting with Omega.
Part number EWS-TX has an adjustment labeled “P4” on the board for calibration at ambient temperature.
If you still have an issue after the adjustment try using a power supply with an output voltage between 8 and 18 volt dc.

The EWS-TX has a note "Not recommended for fast moving air applications." What is considered acceptably low air flow and what is the effect on accuracy as air flow is increased? Does the direction of the air flow relative to the case matter?
Thank you for the inquiry. The EWS-TX is designed for office environment. Not for mounting inside air ducts where fast moving air and possible vibration could damage components. For a sensor designed for air duct or similar application please email request to TEMP@OMEGA.COM.
Best regards,
OMEGA

Does the EWS-RH come with the temperature and humidity sensors included? And also, do they have separate 4-20 mA analog outputs? (one for temperature and one for humidity).
Thank you for your inquiry! Yes, the EWS-RH has internal temperature and relative humidity sensors. They also have separate 4-20mA outputs. Please find the EWS-RH Manual in the Quick Links tab and look to page 4 for wiring examples.
