Question 1: Number of working principles of stress sensors.

Number of stress sensors working principles: When the pressure in the system is higher or lower than the rated safety pressure, the inductive number shows the dish of the pressure sensor in the pressure sensor. Open, when the pressure drops to or rated the rated recovery value, the disc's instant reset, the electrical automatic reset, or simply speaking when the measured pressure exceeds the rated value, the free end of the elastic element generates displacement, directly or after comparison, after comparison Promote electrical components, change the disconnection state of electrical components, and achieve the purpose of controlling the measured pressure. The elastic components used by the number of stress sensors include single -circle spring piping, film, membrane boxes and ripples. Electric components include magnetic sensors, mercury, micro -sensor, etc.

Question 2: The composition of the pressure sensor.

1 The collection component of the sensor pressure differential pressure temperature liquid level

2 High precision, high stable, low -temperature drift amplification circuit

3 A/D conversion module

Question 3: Delivery the fatal problem of the pressure sensor.

Anti -interference is the most important factor that affects the use of pressure sensors. Therefore, the pressure sensor at this stage generally use anti -interference shells, which is better than the stability of the old pressure sensor.

Question 4: Comparison of number showing pressure sensors and mechanical pressure sensors.

The number of stress sensors has high accuracy, good repeatability, long life, no contact, strong corrosion resistance, strong and convenient settings, flexible and convenient, and small drift and small drifting.

Question 5: Compare the pressure sensor with similar products.

1 uses model recognition technology to overcome the pressure of the existing pressure sensor. When the pressure of the existing pressure sensor is super low instantly, the pressure sensor movement causes abnormal pumps.

2 adds the process selection sensor. The bearing process and the closed process can be set to set different thresholds. The threshold of the bearing process settings can be appropriately reduced, thereby solving the problem that the pressure sensor of the side can not be put into use.

3 adds a calibration button. When you check the "calibration button" when you check the intelligent number showing pressure sensor, the micro computer will automatically remember the current pressure value, and set the value as the "smart number showing pressure sensor" settings setting. Value, thereby the test of the pressure sensor.

Question 6: Digital Displayed Terms Related Terms and Introduction

I have introduced the relevant terms of the pressure sensor before, and the terms showing the terms of the pressure sensor and the mechanical pressure sensor are similar. , S.P.D.T (single -knife and double throw), D.P.D.T (double knife and double throw), one in the upper limit (frequent opening), the lower limit one contact (normal closed), the upper and lower limit of two contact HL, the upper limit 2 contact, the lower limit 2 contact, IP (protection level (protection level (protection level To.
