FAQ

What is the function of the ‘K1’ designator in the model number W3-P706H-S2N-T5-K1?

The ‘K1’ code in BETA’s model numbering system typically specifies the process connection. For this model, it indicates a 1/2 inch NPT female connection made from 316 Stainless Steel, offering excellent corrosion resistance.

Is this pressure switch suitable for use with corrosive media?

Yes, the wetted parts, including the 316 Stainless Steel process connection, are designed to be compatible with a wide range of corrosive media. However, always verify chemical compatibility with your specific process fluid against the manufacturer’s material specifications.

How do I adjust the setpoint and deadband on this W3 series switch?

The setpoint is typically adjusted via an internal screw located under the main cover. The deadband (the difference between the trip and reset points) may be fixed or adjustable depending on the specific microswitch option. Always de-energize the circuit before opening the enclosure for adjustments, as stated on the cover.
