FRP5 Thinwall Tip Temperature Sensor

The FRP5 is one of our fastest sensing temperature sensors which uses a 2.1mm diameter sensing tip that is extended for maximum insertion into the fluid being measured.  This helps to ensure this sensor has a very fast speed of response, typically with a time constant of less than 1s.

The “long tip” thin-wall sensor design is made from 316 stainless steel and is fitted with an integral brass collar to ease assembly.  This makes them perfect for potable water applications such as coffee machines and hot taps as well as instantaneous water heaters or showers.

Various lead-wire options and connectors available, call us to discuss.


  • Coffee boilers & machines
  • Hot taps & instant water heaters
