Selection of miniature pressure transmitter

The selection of miniature pressure transmitter should be a good selection of compact pressure transmitter. Several parameters need to be clear: 1. Pressure range; 2. Operating temperature range; 3. Medium to be measured; 4. Measurement Accuracy; 5. Output signal; 6. Pressure range such as interface size, that is, the minimum pressure and the maximum pressure difference to be measured. Generally, pressure transmitters have an overload capacity of 1.5 times. The selection of miniature pressure transmitter should be a good selection of compact pressure transmitter. Several parameters need to be clear: 1. Pressure range; 2. Operating temperature range; 3. Medium to be measured; 4. Measurement Accuracy; 5. Output signal; 6. Pressure range such as interface size, that is, the minimum pressure and the maximum pressure difference to be measured. Generally, pressure transmitters have an overload capacity of 1.5 times. Use temperature range, minimum use temperature and maximum use temperature. Generally, it is -20～80℃. If the temperature is high, other cooling measures are required. The medium to be measured varies with the medium to be measured, and the requirements for the pressure transmitter are different. Such as acid and alkali resistance, ceramic sensors are better. The shell is resistant to acid and alkali, etc. Measurement accuracy, 0.5% accuracy is more for general use occasions. If the measurement is required to be more accurate, 0.2% or 0.1% measurement accuracy can be required. The output signal is what kind of signal the secondary instrument can accept for the relevant use. Most of them use 4-20mA, and there are other output signals such as 0-5V, 0-10V or 0-20mA. The interface size is based on the customer's on-site use conditions, processing the corresponding installation size.
