Product Spotlight: Siemens introduces new features to the SIPART PS2 Valve Positioner

The Siemens SIPART PS2 Valve Positioner demonstrates the versatility and reliability that you have come to expect from Siemens. While Siemens leads the market with safe, uninterrupted performance, we’re striving to develop new technologies to meet the changing market needs and expectations.

With that in mind, this year we are introducing new functionalities to our SIPART PS2 Valve Positioner:

1. Fail in Place Technology
Traditionally, upon loss of power to a valve positioner, the device will fail to an end stop position.

Our new optional Fail-in-Place (FIP) feature causes the valve to remain in the last position when it loses power. This is particularly useful in damper control applications, but can also be beneficial for critical process control valves.

2. Valve Performance Test through a HART Update
New diagnostic features and control improvements via the HART Communication protocol update. The key feature in this update is a Valve Performance Test (VPT). VPT provides hysteresis, non-linearity, non-repeatability, maximum measured error and inaccuracy up/down.

This test will provide a baseline as well as current data on your valve that will help plan upcoming maintenance on your customers’ equipment.

3. Integral Volume Booster (launched in August 2014)
Volume Boosters are typically mounted externally to the valve positioner and are used to boost air flow to the actuator.

Our unique Integral Volume Booster (IVB) directly connects to the SIPART PS2 and eliminates a majority of the fittings and pipe bending required to mount standard external volume boosters. This reduction in piping, fittings and labor helps reduce the overall cost of ownership.
