The PST-A202DN SMART positioner is a 4-20mA positioner used to modulating pneumatic actuators via a proportional signal. The SMART positioner has the option for HART capabilities, which will make it compatible with networking solutions that follow HART protocol. All units have a position transmitter to allow for remote actuator position monitoring. Units feature a small package design for fitting into tight spaces. Local indication is provided via an LCD panel and mechanical pressure gauges are provided.
Ideal Applications Include:
Chemical Processing, Bleach Plants, Aquariums, Mining, Water Treatment, Landfills, Swimming Pools, Power Plants
