Spirax Sarco is helping instrumentation users reduce their energy consumption with their ultra-efficient SP500 positioner with HART communications. This positioner consumes approximately 1% of the air of a traditional electropneumatic positioner and has class-leading low impedance helping to save on controller power. The SP500 digital positioner supports HART communication protocol. This protocol comprises of a digital data transfer and communication over existing 4-20mA wiring, requiring no additional power supply or wiring to the positioner.
