COMET SN164M – Pt1000 Surface Probe -50 to +200 °C, Mini DIN Connector

COMET SN164M – Pt1000 Surface Probe -50 to +200 °C, Class A, MiniDin Connector, Silicone Cable, IP65, Brass Housing Ø 19.5 mm 

The COMET SN164M is a professional Pt1000 surface temperature probe with a MiniDin connector – specifically designed for precise contact measurement of surface temperature on solid materials such as machinery, pipes, plates, heat exchangers, motors, radiators, or tanks. With a measuring range of -50 to +200 °C and high Class A accuracy, it is ideally suited for continuous use in industrial environments, mechanical engineering, HVAC systems, energy applications, laboratories, or anywhere surface temperature needs to be measured directly – without complex installation or drilling.

The Pt1000 sensing element (3850 ppm/°C, Class A) provides maximum accuracy: ±(0.15 + 0.002 × t) °C across the entire range. The brass housing (diameter 19.5 ± 0.1 mm, height 6 ± 0.1 mm) with two mounting holes (diameter 4.3 ± 0.05 mm) allows secure attachment using M4 screws for optimal thermal contact. The shielded silicone cable is heat-resistant, flexible, and chemically resistant – ideal for demanding environments. The MiniDin connector ensures quick and safe connection to COMET measuring devices, data loggers, or transmitters. IP65 protection reliably guards against dust and water jets – suitable even for wet or cleaning-intensive environments.

The probe is maintenance-free, long-term stable, and available with a traceable calibration certificate (according to EN ISO/IEC 17025) – ensuring top quality for critical applications. Installation is simple with two M4 screws – thermal paste is recommended for best heat transfer. Whether for process monitoring, temperature control, alarm systems, or documentation, the SN164M delivers precision, durability, and ease of use. The fast response time (t0.5 <10 s on flat surface without paste) ensures real-time measurement results.
