Product Description

The Dwyer S2-1A is a surface temperature probe for industrial process monitoring, featuring stainless steel 304 construction and a 584 mm lead wire. It delivers ±0.1% accuracy with PT100 RTD sensors across an operating range of -40 to +125°C, suitable for HVAC and equipment diagnostics applications.

Frequently Asked Questions

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

The Dwyer S2-1A surface temperature probe is used for industrial process monitoring, HVAC diagnostics, and equipment troubleshooting. It measures surface temperature on water pipes, low-pressure steam lines, or refrigeration circuits where immersion is not possible. Its stainless steel 304 construction and PT100 RTD sensor provide reliable readings from -40 to +125°C.

What are the specifications of the Dwyer S2-1A surface temperature probe?

The Dwyer S2-1A features a stainless steel 304 probe, 25 mm length, 6.3 mm diameter, and a 584 mm lead wire with 22 AWG stranded Teflon® conductors. It uses a 2252Ω NTC thermistor with ±0.2°C accuracy at 25°C. Operating temperature range is -40 to +125°C. The probe is suitable for HVAC and industrial surface temperature measurement.

Where to buy the Dwyer S2-1A surface temperature probe in Singapore?

You can source the Dwyer S2-1A surface temperature probe through 3G Electric in Singapore. We supply genuine Dwyer instruments and handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this model. We provide reliable sourcing for industrial measurement equipment.

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

To install the Dwyer S2-1A, clean the surface and apply thermal paste for optimal contact. Secure the probe using a clamp or adhesive rated for the operating temperature range of -40 to +125°C. Route the 584 mm lead wire away from sharp edges and high-EMI sources. Connect the 22 AWG wires to your controller per the thermistor input specifications.
