ER681

ER681 are high performance pressure sensors and electronic pressure switch. They are mainly composed of an ASIC signal conditioning chip, a pressure sensitive core and a pressure port. The ASIC chip is composed of 16 pins arranged in a package and composed of various precision resistors and capacitors that can produce a stable output voltage value according to the pressure applied. The pressure sensitive core is a pressure sensitive core made of metal, ceramic or composite material with a certain sensitivity. The pressure port is connected to the outside world to collect the pressure data. The ER681 pressure sensing device is a multifunctional electronic component with extensive application fields.

1. Common Application Fields of ER681

ER681 pressure sensor mainly used in the measurement of pressure, liquid level, flow and other physical parameters in the process automation industry, widely used in the manufacture of pressure transmitters, pressure switches, and pressure controllers in manufacturing plants, factories and laboratories. It can also be used in machinery conditions such as lubrication system, operating system, start and stop operations, overload protection, and equipment maintenance.

2. Working Principle of ER681

ER681 working principle is based on the Wheatstone bridge principle. When the pressure is applied to the two measuring electrodes of the pressure core, a bridge circuit will be formed, and the resistance of the two measuring electrodes becomes unbalanced. The unbalanced voltage signal is outputted through the ASIC chip. The output voltage value is related to the pressure, and its linear scale is 0-5V. The voltage value is converted into pressure value through calibration to achieve the purpose of accurate measurement. ER681 also has a wide range of application temperatures, with a wide range of temperature levels of -40~125°c.

3. Advantages of ER681

ER681 pressure sensors have a number of benefits due to its advanced manufacturing technology. Its advantages include high resolution measurement, excellent temperature compensation, long service life, anti-interference performance and cost performance. Due to its excellent stability, the temperature coefficient is only 0.3%/°C, ensuring high resolution measurement accuracy and anti-interference performance. In addition, the mounting structure is simple, convenient for users to install or repair. Meanwhile, the ER681 pressure sensor can be widely applied in many harsh and humid environments.

4. Conclusion

In conclusion, ER681 pressure sensing devices are a reliable, cost-effective option in many process control applications. Its high resolution measurement and excellent temperature compensation performance, long service life, anti-interference performance and cost performance guarantee make it an important component of process control systems. As more and more industries move towards automation, the need for pressure sensing devices and components will rise. ER681 can be a vital tool for many process control systems.
