1.2 Description of SmartCal Positioner.
The SmartCal Smart Valve Positioner is an electro-
pneumatic servo system that continuously controls
the position of a valve based on a 4 to 20 mA input
signal. The SmartCal is an instrument that derives its
power directly from a control systems current loop.
The instrument senses valve position via a non-
contact Hall Effect sensor and controls valve position
through a current to pressure transducer.
The SmartCal is available in two versions, HART®
and non-HART. The non-HART version allows
calibration of the instrument through an on board
keypad. The HART® version allows calibration and
access to on-line diagnostic information via
Rosemount 375/475 hand-held terminal or through
software.
The positioner has a local liquid crystal display which
indicates valve position and set-point in percentage
of full span. It also indicates whether the positioner
is in calibration mode.
The SmartCal has the capability to monitor operation. If a failure condition occurs,
an error message is displayed on the local liquid crystal display.
There are several accessories that can be integrally supplied with the SmartCal.
Among these are a 4 to 20 mA analog output, and a set of hermetically sealed non-
contact limit switches.
