Spirax Sarco has released the SP500 HART® electro-pneumatic digital positioner supporting HART® communication protocol. The protocol allows for digital data transfer and communication over existing 4-20mA wiring, requiring no additional power supply or wiring to the positioner. Through the protocol, the positioner can be configured and process parameters updated or modified remotely using a PC or handheld device.
