1. When measuring the liquid pressure, in order to prevent the sensor from being damaged by overpressure, the device position of the sensor should prevent the impact of the liquid.
2. When measuring steam or other high-temperature media, it is necessary to connect a condenser such as a buffer pipe.
3. The impulse pipe should be installed in a place where the temperature fluctuation is small.
4. When wiring, in order to prevent rainwater from leaking into the transmitter housing through the cable, it is necessary to pass the cable through the waterproof joint or winding pipe and tighten the sealing nut.
5. Prevent the sensor from coming into contact with corrosive or overheated media, and prevent residues from accumulating in the catheter.
6. When measuring the liquid pressure, in order to prevent the accumulation of slag, the pressure port should be opened next to the process pipeline.
7. When freezing occurs in winter, in order to prevent the liquid in the impulse port from expanding due to icing volume, resulting in the loss of the sensor, the sensor installed outdoors should adopt anti-freezing methods.
8. When measuring gas pressure, in order to facilitate the simple injection of accumulated liquid into the process pipeline, the sensor should be installed in the upper part of the process pipeline, and the pressure port should also be opened at the top of the process pipeline.

The main classification of current sensors is ifm
(1) Resistance shunt: It is actually a resistance with a very small resistance value, when there is a current passage period, according to Ohm's law, the voltage occurs in the resistance, and the current size is known according to the measured voltage value. The resistance shunt has high precision, fast response, low cost, simple use, and disadvantages ...

Differential pressure sensor function – ifm sensors
A differential pressure sensor is a sensor used to measure the difference between two pressures, usually used to measure the pressure difference between the front and rear ends of a device or component.
A typical application of differential pressure sensors is to measure the difference in exhaust pressure between the front and rear channels of the exhaust particulate trap of a passenger car engine.

What are the characteristics of smart sensors?
1. High precision and high quality
Assuming that the data information collected by the sensor makes a mistake, it is equivalent to making a mistake from the source, and the transmission, analysis and use of all the data behind it are meaningless, so the accuracy and quality of the sensor are guaranteed.

Sensors, temperature sensors, RTDs and thermocouples – ifm
RTDs and thermocouples are the most commonly used temperature sensing elements for temperature sensors. The operating principle of thermocouple temperature sensor is that the two ends of the contact surface of two kinds of incompatible metals produce a weak and weak voltage when the temperature is inconsistent, and the temperature is measured by expanding the electric, which is not necessary to measure the high temperature. RTD Temperature Sensors ...
