Reverse output:
The high-performance line of I/P
transmitters utilizes an internal feedback loop to
ensure accurate operation. The feedback loop consists
of an internal pressure transducer that samples the
unit’s output pressure and compares it to the input
signal. This allows the unit’s output to track the input
signal. Other I/P transmitters, such as our original
IPT, IPH and IPX models, rely solely on mechanical
positioning. This is what makes the IPT
2
, IPH
2
and IPX
2
highly desirable. Since the feedback loop requires
power to operate, when there is no input power to the
unit, the pneumatic output will be shut off . Units that
use mechanical positioning only, will typically still have
a pneumatic output (18 PSIG typically) when power is
removed. This is not an issue except for those users
that rely on this elevated output (18PSIG) to maintain
a valve’s position upon the unexpected loss of input
signal (4-20mA). In such cases, the IPT
2
, reacts
diff erently by shutting off the pneumatic output.
