Frequently Asked Questions

What is the Dwyer S2-1C surface temperature probe used for?

The Dwyer S2-1C is a surface temperature probe for industrial process monitoring, ideal for measuring temperature on water pipes, low-pressure steam lines, or refrigeration circuits in HVAC and manufacturing applications where immersion is not possible.

What are the specifications of the Dwyer S2-1C?

The Dwyer S2-1C features a stainless steel 304 probe, 25 mm length, 6.3 mm diameter, 584.2 mm wire length, 22AWG wire gauge, and a thermistor with ±0.2°C accuracy at 25°C. Operating temperature range is -40 to +125°C.

Where to buy the Dwyer S2-1C in Singapore?

3G Electric supplies the Dwyer S2-1C surface temperature probe to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on this thermistor model.

How to install the Dwyer S2-1C surface temperature probe?

Mount the Dwyer S2-1C probe directly on the pipe surface using a suitable clamp or bracket, ensuring good thermal contact. Route the Teflon-insulated wires away from sharp edges and secure them to prevent strain. Follow standard industrial wiring practices for RTD or thermistor connections.
