COMET SN164C – Pt1000 Surface Probe IP65, -50 to +200 °C

COMET SN164C Pt1000 Surface Probe CINCH 

The COMET SN164C (Pt1000TG7/C) is a professional surface probe with a CINCH connector designed for precise temperature measurement on solid surfaces. Specially developed for continuous operation, it measures from –50 to +200 °C (must not be exceeded) and, with full IP65 protection, is suitable for humid or dusty environments. The brass housing with two M4 mounting holes can be securely fastened with screws – ideal for pipes, machines, motors, radiators, metal plates, and tank walls, or anywhere direct surface contact is required.

The Class A Pt1000 sensor (±0.15 + 0.002 × |t| °C) ensures the highest accuracy and long-term stability. The shielded silicone cable (1 meter standard) remains flexible up to +200 °C and provides noise-free signal transmission. The flat measuring head (only 6 mm high, Ø 19.5 mm) guarantees optimal thermal contact and rapid response time (t0.5 < 10 s on aluminum prism without paste).

The CINCH connector enables a quick, secure connection to COMET transmitters, data loggers, or any Pt1000 input system. The probe is universally suitable for heating, HVAC, solar, motor, and process technology – for non-aggressive environments and extremely reliable performance.

Installation:

Securely mount on the surface using one or two M4 screws. For best thermal contact, apply thermal conductive paste (optional). The silicone cable remains flexible and resistant up to +200 °C – perfect for tight or dynamic installations.

Summary:

• The Pt1000TG7 temperature probes are designed for measuring the surface temperature of solid materials.
• The maximum operating temperature range is from –50 °C to +200 °C.
• These limits must not be exceeded, even briefly.
• The connection cable is silicone‑insulated and shielded.
• The probes react quickly to temperature changes.
• Mounting is performed with one or two M4 screws.
• The probes are intended for use in chemically non‑aggressive environments.
• The installation method must consider the temperature and chemical resistance of the housing and connection cable.
