COMET Pt1000 flue gas probe -50 to +400 °C, RCA connector

COMET SN270C – Pt1000 Flue Gas Probe –50 to +400 °C, Teflon Cable 1 m, CINCH Connector 

The COMET SN270C (Pt1000TR050M/C) is a specialized Pt1000 flue gas and high-temperature probe with a CINCH connector, designed for demanding use in chimneys, furnaces, wood gasifiers, pellet boilers, heating boilers, and exhaust systems. With a wide measuring range of –50 to +400 °C (short-term up to +450 °C at the measuring tip) and a Teflon-insulated cable (max. +260 °C at the cable), it is perfectly suited for precise monitoring of flue gas, exhaust, and process temperatures.

The Pt1000 sensor, Class A (±0.15 + 0.002 × |t| °C up to +250 °C), ensures maximum accuracy and long-term stability. The long stainless-steel measuring stem (90/130 mm × Ø 6 mm, DIN 1.4301) with an 8 mm spacer ring is corrosion-resistant and penetrates deeply into the gas flow. The shielded Teflon cable (1 meter standard) remains heat-resistant and flexible. The CINCH connector allows quick and reliable connection to COMET transmitters, data loggers, or any Pt1000-compatible input unit.

The probe is fully IP64 rated – perfect protection against soot, condensate, and splash water. The extremely fast response time (t_0.5 < 5 s in flowing water) ensures accurate control and rapid reaction to temperature changes. Ideal for fireplaces, solid-fuel boilers, pellet systems, biomass plants, heating optimization, or emission measurement.

Summary:

• The temperature sensors are designed to measure flue gas and exhaust temperatures in fireplaces, furnaces, and boilers.
• The Pt1000TR050M temperature sensors are suitable for measuring the temperature of gaseous and liquid media.
• The operating temperature range of the sensor is between –50 °C and +400 °C.
• A maximum temperature of up to +450 °C may be briefly exceeded (related to the active measuring area, limited by the spacer ring).
• The temperature in the area of the Teflon-insulated lead must not exceed +260 °C.
• The sensors comply with protection rating IP64 according to EN 60529.
• They are suitable for temperature measurements in chemically non-aggressive environments.
• When selecting the installation location, a housing and cable resistant to temperature and chemicals must be considered.
