Clamp on Temperature Sensors
Non-intrusive temperature sensor to suit various requirements.
The RTD720 Strap-On Sensor is a surface style RTD strap-on sensor with cable and flying leads. This surface sensor can be secured to a pipe or tube using jubilee hose clip banding and a screw box. The RTD720 surface RTD is available with either PTFE, PFA or fibreglass cable and is terminated with tails. The RTD720 has an available temperature range between -196°C and +650°C. A variety of materials and versions are available. By far the most common RTD Fluidic supply is the platinum resistor type, Pt100. A Pt100 is also defined by its resistance at 0C, i.e. 100hms. The resistance value at each temperature point is compliant with a regulated standard. The European standard for Pt100 is IEC 60751.
RTD720 Strap-On Sensor. Typical choices include:
Through our H&B Sensors partnership, Fluidic also offer Insulation Jackets to go over the sensor. By insulating correctly, effects of thermal convection from the outside environment can be mitigated, ensuring an accurate and reliable temperature measurement.
As the output of a RTD is resistance dependant, consideration should be given to the lead wires within the probe from the sensor itself. For this reason, Fluidic more commonly supply 3 or 4 wire RTD sensors. The 3rd and 4th wires are used for resistance compensation. Where the signal is to travel any distance, Fluidic recommend the use of a 4/20mA transmitter. We supply various transmitter options and can supply the transmitter and RTD temperature sensor pre-assembled.
Fluidic are the Scottish and Northern England partner for H&B Sensors. We also have an exclusive agreement for supply to the UK nuclear industry. Our instrumentation engineers are product trained and are able to help with instrument selection within the full H&B Sensors supply scope. Most products can be custom made for application.
