COMET DSTGL40/C – Pt1000 temperature probe –30 to +80 °C, RCA connector

COMET DSTGL40/C – Digital Pt1000 Temperature Probe –30 to +80 °C, ±0.5 °C, 40 mm length, CINCH connector, for P-Line WebSensor

The COMET DSTGL40/C is a compact digital temperature probe with a CINCH connector, specially developed for the P-Line WebSensor series (P8511, P8541, P8641, P8552, P8652). It precisely measures air or process temperature within the range of –30 to +80 °C (±0.5 °C) and is designed for non-condensing environments with 0–100% relative humidity. The short and slim measuring rod (length 40 mm, Ø 5.7 mm) is ideally suited for direct insertion measurements in airflows, pipes, small containers, or tight installation spaces.

The probe is fully digital and can be replaced without recalibration – simply plug it in, and the WebSensor automatically detects it. All P8xx1 devices are supported from firmware version 4-5-5.0 onwards. This makes it the perfect extension for Ethernet-based temperature monitoring with web interface, COMET Cloud, Modbus TCP, and remote alarm.

Optionally available with various cable lengths (1 m standard, up to 10 m) – flexible for any installation situation. The probe is IP20-protected and designed for dry to slightly humid indoor environments. It operates reliably across the full operating temperature range of the sensor – ideal for building automation, storage, production, or climate control.

Why the COMET DSTGL40/C is the best digital short probe for P-Line:

  • Digital interface – plug & play, no calibration required
  • Precise measurement – ±0.5 °C across the entire range
  • Wide measuring range – –30 to +80 °C
  • Compact rod – only 40 mm long, Ø 5.7 mm – perfect for tight spaces
  • CINCH connector – secure and quick connection
  • Compatible from firmware 4-5-5.0 – for all current P8xx1 models
  • Flexible cable lengths – optional 1 m to 10 m
  • IP20 protection – for dry to slightly humid environments
  • Original COMET accessory – 100% compatible & reliable
  • 3-year warranty
