Zero drift of high-frequency pressure sensors – we are blessed
There are several reasons for the formation of zero drift of high-frequency pressure sensors:
1. There are bubbles or impurities in the adhesive layer of the strain gauge
2. The function of the strain gauge itself is unstable
3. There are virtual solder joints in the circuit
4. The stress release of elastomers is incomplete; In addition to the magnetic field, ...

Wiring of weighing strain gauge tension and compression sensors – we are in control
Strain gauge tension and compression load cells are available in two different input and output wiring methods:
The first is the four-wire connection method.
The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.

Fault detection of load cells and corresponding replacement – we are blessed
1. Fault judgment
When the electronic scale presents the following phenomena, it is necessary to see whether the load cell presents a problem.
1) If the electronic scale does not show zero, the display screen continues to shine or show zero in the future, and the weighing number does not appear when weighing.
2) Electric ...

How to use high-temperature pressure sensors - we are blessed
1. It is necessary for the sensor to be properly installed
Damage to high-temperature pressure sensors is usually caused by their installation in improperly machined holes. When a sensor is loaded into a hole that is too small or has a migraine, it may damage the sensor diaphragm and cause the instrument to not function properly.
Can...

The correct way to test the output of the sensor – the sensor
1. Test for NPN output sensor
The NPN sensor output, also known as OC gate output, is based on the principle of open collector output of a transistor.
The principle of NPN type OC gate output is whether the output of the NPN transistor and GND are short-circuited. When the control is active, the transistor is turned on, the output and the GND ...
