Introduction

Gauge made of steel, Aluminium block, double-action, 1/4-18 NPT, scaled in MPa, bar and psi.

SIPART PS2 electropneumatic positioner in flameproof stainless steel enclosure 316L with stainless steel gauge block (optional) The SIPART PS2 electropneumatic positioners are used to control the process valve or damper position of pneumatic linear or part-turn actuators or via positioning cylinder according to the setpoint specification. A digital input can trigger holding of the position or approach of the safety setting of the process valve.

Function
● The electropneumatic positioner, in combination with the drive, forms a regulation system. The current position of the drive is detected using a servo potentiometer and is sent back as actual value x. The actual and target values are simultaneously displayed
on the digital display.
● The setpoint w forms a current applied to the positioner, which in two-wire mode is also used to power the positioner. In 3- and 4-wire mode, power is supplied through a 24-V power input.
● The positioner works as a predictive five-point positioner, through whose output value ±Δy the integrated valves can be controlled by pulse length modulation. 

● These positioning signals cause pressure changes in the drive chamber(s) and thus a repositioning of the drive until the regulation deviation returns to zero. 

● Using three buttons and a digital display with the housing cover removed, operation (manual mode) and configuration (structuring, initialization, and parameterization) can be performed.
● By default, the basic unit has a binary input (BE1). This binary input can be individually configured and used e.g. to block the control levels.
● To be able to use the positioner in a variety of mechanically different rotational and linear actuators, it has a friction clutch and a switchable gear.
