What is a Strain Gauge?

The resistance of a strain gauge changes when force is applied and this change will give a different electrical output. Strain gauges use this method to measure pressure, force, weight and tension. When external forces are applied to a stationary object there are two forces present; stress and...

Difference Between PT100 and PT1000

The numerical reference (100 or 1000) pertains to the sensor’s Ohmic value at 0°C. When to use a PT100 and PT1000 A Pt1000 has a much higher resistance level therefore the distorting effect of the resistance in the lead wires will be less significant overall as it contributes to a...

OIML and NTEP Approved Load Cells

What are OIML and NTEP Load Cells? Load cells being used in commercial and legal applications must legally be certified as “Legal for trade” by an approving body to ensure they meet the required regulations. This can apply to both load cells and associated electronics used within...

What is an Encoder

Encoders are used within a wide range of equipment throughout many different industries and convert motion into an electrical signal to be read by the system control device enabling a function or process.  Encoders usually comprise of a plastic or metal housing to protect the electronics,...
