The FRP3 sensor design is commonly found in many gas-fired hot-water boilers. Through being manufactured in high-volumes, this sensor is relatively low-cost and so can be utilised across a range of temperature sensing applications.
The FRP3 sensor is generally supplied with an 1/8″BSPG thread and integral connector, though metric threads and flexible lead-wire options are also readily available. This sensor can be supplied with various NTC thermistors or with Pt100/Pt1000 platinum elements.
These immersion sensors are available in brass, nickel-plated brass or stainless steel with a typical time constant (Tc) of around 5 seconds.
