Rangeable / Programmable Transmitters
PMC/STS offer rangeable transmitters where the process pressure might change and maximum output resolution is required, or to standardize on a single type of device to satisfy a multiple number of installations. These are generally programmable through a digital interface such as RS485.
The PTM series is a high precision pressure transmitter, fully programmable over a dynamic range of 4:1 based on the full scale selected. The digital compensation provides high accuracy and general performance including linearity, hysteresis, repeatability and thermal effects while still providing a conventional 4-20mA 2-wire output for industrial and process applications.
The PTM/RS485 series is a fully digital programmable pressure transmitter providing the option of a 4-20mA analog output in addition to the standard RS485 MODBUS protocol. The transmitter offers the total accuracy of ≤ ± 0.15% FS including linearity, hysteresis, repeatability and thermal effects. The PTM also provides a precision temperature output thus offering a very high performance pressure/temperature sensor at a very affordable price.
