Wiring

Tips: Precautions For Explosion-proof Temperature and Humidity Sensor Use

To turn the screw on the top cover, press the screw with a screwdriver and then turn the screw.
When connecting terminals, do not strip the cables too long, and do not expose the copper wires directly inside the product to avoid short-circuit risks.
Disconnect the power supply before connecting the circuit.
Do not touch internal components directly with hands or metal objects.
After the installation is complete, check the screws on the cover and whether the waterproof connector is locked. The wire diameter must be 4-8mm.
5 minutes after switching on the power supply, the calibration operation will be carried out. Otherwise, the data output will not be accurate.

Explosion-proof transmitter

We are looking for an explosion-proof temperature and humidity transmitter, equipped with a display screen, suitable for pipeline installation, and featuring a 4-20 mA output signal, capable of operating in ambient temperatures above 60 degrees Celsius. Does your company have a product that meets our requirements?

ATO Responded

Our explosion-proof temperature and humidity sensor, 4-20mA, SKU: ATO-TAHS-EP, can be made with an extension probe and thread. Could you please confirm if this meets your requirements? Could you tell us the thread specifications required for pipeline installation? What is the probe length?

About probe

Hi, I am looking at your explosion proof temperature and humidity sensor ATO-TAHS-EP. I am curious if it comes with the probe itself, I just don't see anything confirming that and most pictures show it without the probe. Additionally, is there any offset to the output depending on temperature? Thank you.

ATO Responded

Our temperature and humidity sensor ATO-TAHS-EP does Not have a probe. It directly displays the temperature and humidity values from the sensor output, and there is No temperature offset.
