Hello,
I have a positioner from Emerson Fisher type DVC2000 with HART protocol. I want to use instead of this positioner an equivalent Siemens SIPART PS2 positioner. I have selected one whose catalog number is
6DR5010-0NG00-0AA0
. I have compared datasheets from both products and I confused for one this that the position ability is defined in the products` datasheets differently.
Emerson Fisher DVC2000
Stem Travel
Minimum:6.35 mm (0.25 inch)
Maximum:606 mm (23-7/8 inches)
Shaft Rotation
Minimum:45
Maximum:90
Siemens SIPART PS2
Rotation angle of the part-turn actuator :30 Degree...100 Degree
Stroke range of the linear actuator : 3 mm...130 mm
Are these parameters corresponding to each other?
Are these products coinciding technically each other?
I am waiting your precious help.
(I have added the basic datasheets for both products)
Hello, thank you for your inquiry regarding the compatibility of the Siemens SIPART PS2 (6DR5010-0NG00-0AA0) with your existing Emerson Fisher DVC2000 positioner.
You are right to compare the travel/rotation ranges. While the units differ, they can be made to correspond, but careful consideration is crucial. Here's a breakdown:
Technical Coincidence: The products are not directly "coinciding" (1:1 replacement) without verifying the specific application requirements, particularly the stem length needed for full travel. You MUST ensure the chosen SIPART PS2 has a sufficient stroke to match the DVC2000's full range, or you'll have control limitations.
Recommendation: I strongly recommend reviewing the SIPART PS2 configuration guide and using the Siemens Valve and Actuator Sizing Tool (VAST) to confirm a suitable PS2 model based on your valve's specifications and required control characteristics. Link to Siemens VAST
Please provide your valve’s travel requirements, and I can further assist you.
