Frequently Asked Questions
Common questions about Winters pressure switches
What is the Winters WPS pressure switch lineup?
The WPS family is Winters Instruments' complete range of mechanical pressure switches: 2WPS/4WPS general purpose, 5WPS and 10WPS differential, 9WPS compact explosion-proof, 3WPS/8WPS vacuum and low pressure, 6WPS/7WPS medium and high pressure, plus PEC/1WPS OEM and WPS HVAC models.
Is the 9WPS suitable for hazardous locations?
Yes. The 9WPS is a compact explosion-proof switch with UL/CSA approval for Class 1 Division 1 hazardous locations, covering vacuum to 10,000 psi with SPDT or DPDT outputs and NACE-compliant options for sour gas service.
How does the 9WPS compare to CCS pressure switches?
The 9WPS delivers comparable explosion-proof performance with a proven install base across Western Canada at a better price point. Intrepid stocks the 9WPS locally, so lead times are typically much shorter as well.
What warranty do Winters pressure switches carry?
All Winters-manufactured products come with an industry-leading 5-year warranty, backed by Winters' third-party audited quality assurance program.
Are Winters pressure switches stocked in Canada?
Yes. Winters maintains stock in Edmonton and Toronto, and Intrepid carries additional local stock of high-demand models like the 9WPS. Combined with same-day quoting, this means very fast turnaround for Western Canada customers.
Can Winters switches handle differential pressure applications?
Yes. The 5WPS covers general differential applications, the 10WPS provides explosion-proof differential switching, and commercial WPS differential models are available for HVAC and building systems.
How do Winters pressure switches differ from the Ceraphant compact pressure transmitters?
Winters WPS switches are mechanical/electromechanical switches that open or close a contact at a set pressure — simple, robust, and cost-effective. The Endress+Hauser Ceraphant line provides continuous electronic pressure measurement with configurable outputs. Intrepid can help you choose the right technology for your application.
Can Intrepid help me spec the right pressure switch?
Absolutely. Intrepid has 10+ years of Winters product expertise in-house, offers same-day quoting, and can review P&IDs to recommend and quote the right switches for your project.
