Designed for the oilfield environment, pneumatic pressure switches manufactured and distributed by K-Dyne Inc. offer sensing ranges from 10 psi to 10,000 psi. Equipped with a piston sensor, the switches feature an ambient temperature range of -20 to 180F, set point deviation of plus or minus 1 percent, and deadband of 5 percent.
Featuring all stainless steel construction, Ruelco's pneumatic pressure switches are ATEX certified and available as high flow pressure switches, hydraulic pressure switches, electric pressure switches, or differential pressure switches. The high flow switches feature a standard base range of 10-10,000 psi, an operating pressure range from .5 to 20,000 psi, and Cv factor of .090. All the switches are sued to detect and react to high or low level signal from a flow source.
