Temperature Elements

Providing a complete range of thermocouples and resistance thermometers, including standard PT100’s, clamp on, tubeskin thermocouples and multipoint thermometers.

Temperature Switches

A robust device used to open or close a mechanical or electrical switch when a high or low preset temperature has been reached.  A low cost way to control temperature critical applications.

Temperature Gauges

We have partnered with Wika for mechanical dial thermometers and digital indicators to provide operators and engineers with process critical temperature information and alarm control.


Application knowledge is critical in thermowell design to prevent failure and ensure product longevity. We can provide engineering support to help you select the right specification.

Understanding Basic Magnetic Reed Switch Operations for Float Switches

Magnetic Reed Switches and Float SwitchesFloat switches are fundamentally a basic level control product often containing a reed switch to perform the required level control action.  The most confusing part in selecting a float switch is determining the magnetic reed...

Types of Float Switches

Different Types of Float Switch and Their PricesThere are a number of different types of float switches, each with their own advantages and disadvantages.  Most designs can be made to different specifications to suit the ruggedness requirements of an application....

Train level measurement, gauges and indicators

To solve a specific problem with access and the lack of height between a fuel tank and the trains body, AMS have modified the head of our approved level sensors to allow fitting in confined spaces. This development also removed the need for the transmitter to be located in a separate box on the side of the tank and allowed the sensor to be wired directly to the indicators, saving significant additional costs in materials and wiring time.

Train level measurement and control

Advances in the way instrumentation can be powered due to processing capabilities at reduced power levels, combined with the ever-continuing miniaturisation of electronics capability, has created the opportunity for rail companies to consider more modern electronic/digital technology as an alternative to the traditional methods for level measurement.
