PTM380 Pressure Sensor
PTM380 intelligent pressure transmitter is an intelligent pressure measuring product with high accuracy and stability.
It adopts all welded OEM oil filled core body and ADI and combining the special chip microprocessor technology development, has the scene display, data processing, zero, full scale adjustment software, set the parameters of the permanent preservation, 4 ~ 20 ma output and communication functions, such as small volume, high precision, light weight, wide coverage range, suitable for various industries need to precision measurement of fluid pressure.
The product works in two-wire mode, which can directly replace the analog two-wire 4-20 madc output transmitter.
Features:
1. RS485 communication interface or HART communication protocol is optional
2. Support networking applications
3. Adopt digital compensation and nonlinear correction technology
4. No moving parts, reliable performance
5. Provide rich pressure range with low, medium and high pressure
6. Excellent on-site interchangeability, can be customized according to customer requirements
