selective formaldehyde gas module hcho module price is actually a device that converts a mass signal into a measurable electrical signal output. When using the sensor, the first consideration should be the actual working environment in which the selective formaldehyde gas module hcho module price is located. This is very important for the correct selection of selective formaldehyde gas module hcho module price. It is related to the normal operation of the sensor, its safety and service life, as well as the reliability and safety of the entire weighing instrument. There are qualitative differences between the old and new national standards regarding the basic concepts and evaluation methods of the main technical indicators of selective formaldehyde gas module hcho module price.

selective formaldehyde gas module hcho module price quality judgment:

After long-term use, the weighing equipment may produce inaccurate weighing results. Usually, we have to solve these problems through the calibration of the weighing controller. But sometimes, no matter how it is calibrated, the weighing scale body cannot return to normal. At this point, we have to conduct a detailed study from all aspects of the weighing mechanism, whose core component is the selective formaldehyde gas module hcho module price.

The current weighing equipment generally uses resistance strain gauge selective formaldehyde gas module hcho module price (analog) as the core component of the weighing mechanism. It uses the Wheatstone bridge principle to convert weight signals into linearly varying electrical signals. There are typically four lines. The input is an excitation voltage of 5-10V (power supply voltage), and the output is a weight signal measured in "mV". The following editor will show you how to determine the quality of the selective formaldehyde gas module hcho module price:

One: Observation

Observe whether the sensor is deformed or cracked. If these situations occur, you need to contact the manufacturer to replace the new sensor.

Ii. Measurement Methods for Line Input and Output:

Locate the sensor connection terminal in the weighing controller (weighing instrument) and determine the sensor connection circuit

Under normal circumstances, the excitation voltage (between EXC+ and EXC-) is 5-10V, and the idle output voltage of the device (between SIG+ and SIG-) is close to 0, which is less than the maximum output of the sensor. The maximum output of the sensor = excitation voltage * sensor sensitivity. The sensitivity of the sensor for automatic checkweighers is mostly 2mV/ V. If it exceeds this range, please contact the service provider to apply for sensor replacement.
