Product Description

Dwyer S2-1E is a surface temperature probe featuring a Pt 1000Ω RTD sensor with ±0.1% accuracy at 0°C, operating from -40 to +125°C. Stainless steel 304 construction with 584 mm wire length suits industrial process monitoring and HVAC applications.

Frequently Asked Questions

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

The Dwyer S2-1E surface temperature probe is used for measuring temperature on pipes in HVAC, low-pressure steam, and refrigeration circuits. Its Pt 1000Ω RTD sensor with ±0.1% accuracy at 0°C makes it suitable for industrial process monitoring where immersed portions are inaccessible.

What are the specifications of the Dwyer S2-1E probe?

The Dwyer S2-1E features a Pt 1000Ω RTD sensor with ±0.1% accuracy at 0°C, operating from -40 to +125°C. It has a stainless steel 304 probe measuring 25 mm long by 6.3 mm diameter, with 584 mm Teflon®-insulated wire leads.

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

3G Electric supplies the Dwyer S2-1E surface temperature probe to Singapore. We handle sourcing, logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on this Pt 1000Ω RTD probe.

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

Mount the Dwyer S2-1E probe directly against the pipe surface using a clamp or bracket for good thermal contact. Ensure the stainless steel 304 probe tip contacts the pipe firmly. Route the 584 mm Teflon® wires away from sharp edges and secure them to prevent strain.
