Sensors for Mobile Vehicle Applications

The term “Mobile Vehicle” can be used to describe vehicles which are non-automotive and include tractors and other agricultural machinery, mobile cranes, earthmovers, transport buses and other heavy-duty machinery. The main two types of sensors which are often used within mobile...

Weight Sensors

Weight sensors are available in different sizes and capacities which enables them to suit different kinds of weighing applications. Types of weight sensors Some of the most popular different types of weight sensors we offer are; Single point – single point load cells or weight...

What is a Pressure Transducer?

A pressure transducer converts pressure into an analogue electrical signal. Many of them use internal strain gauges bonded to an internal diaphragm. When pressure is applied through the pressure port, the diaphragm will deflect and the strain gauges will be compressed altering the output signal...

Types of Sensors

Sensors are used throughout almost every industry for applications which we come into contact with on a daily basis as well as more industrial and specialist applications. Sensors can be found in the home, the office, in our cars, buses, trains, trams, computers, medical facilities, labs, power...

What is a Thermocouple?

Thermocouples are part of our product portfolio here at Variohm.  How does a Thermocouple work? A thermocouple is constructed of two different metals joined at both ends. To measure temperature, one end of the thermocouple is exposed to heat, when this happens there is a continuous...

What is a Piezoelectric Sensor?

“Piezo” is Greek for “press” or “squeeze” so a piezoelectric sensor effectively measures compression using the piezoelectric effect.  A piezoelectric sensor converts physical parameters - for example, acceleration, strain or pressure into an electrical...
