JS Probe - for use in flues and boilers, temperature of gases below 600°C
Introduction
The JS probe is a heated probe, intended for use in flues and boilers where the temperature of the gases are below 600°C. It incorporates a heater to maintian the sensor at its working temperature, even if the gas is at a much lower temperature.
Applications
The features of the JS probe include:
- Heater sealed in a stainless steel can, isolating it from corrosive flue gases.
- Porous stainless steel filter to minimise dust build-up on the sensor.
- Gas inlet for calibration gases.
- Purge facility, to clean the filter in-situ.
- Modular construction for simple maintenance.
- Compact design, allowing installation in small or large flues.
- Integrated thermocouple, enabling accurate temperature control of the heater.
Specifications
The JS probe requires a separate user-supplied instrument panel providing power and temperature control for the heater, purge timing and purge gas.
