Series DA/DS Bourdon Tube Pressure Switches
Actualizado: 2024-01-18
Customers tell us that the Series DA/DS Bourdon Tube Pressure Switches are the best pressure switches made. The Mercoid DA/DS Series is one of the world’s broadest lines of pressure switches. The DA/DS Series has extremely high sensitivity and great repeatability. The DA Models are equipped with two external adjustments, one for setting high pressure operating point, the other for setting low pressure operating point. Deadband, the difference between high and low setpoints, is adjustable over the full-scale. The DS Models are equipped with a single external adjustment for setting operating point only. For mercury-free switches we offer the snap action switch. Hermetically sealed mercury switch also available.California Residents: Click Here for Proposition 65 WARNING.

Series SA1100 Diaphragm Operated Pressure Switches
Actualizado: 2024-01-18
The Series SA1100 Diaphragm Operated Pressure Switches are weatherproof and explosion-proof in one economical enclosure. Extremely rugged construction assures excellent reliability in chemical, petroleum and industrial plants. New design also provides burst pressure protection to 3000 psi (2006 bar). The rolling diaphragm design maintains a constant effective area to minimize friction. This results in a minimum deadband as low as 5% of full-scale. Since many applications require higher deadbands, the SA1100 includes a separate adjustment of this when necessary. A pump being used to control liquid level in a tank would be a typical situation where this feature would be important. Both setpoint and deadband adjustments are protected, yet clearly visible behind a clear polycarbonate window and are fully isolated from the electrical components for additional safety. A 7/16\" open-end wrench is the only tool required to change settings. Terminal blocks are provided for switch wiring connections and both internal and external ground screws are included. Standard housing is weatherproof to NEMA standards 1 through 4X and 13; explosion-proof to NEMA 7, Class I, Groups B, C & D; NEMA 9, Class II, Groups E, F & G. Optional construction adds drain to meet NEMA 3R IP54.
Series 1000W Weatherproof Diaphragm Operated Pressure Switches
Actualizado: 2024-01-18
With extremely rugged construction the Series 1000W Weatherproof DiaphragmOperated Pressure Switch provides excellent reliability in chemical, petroleum and

Series H2 Dual-Action Explosion-proof Pressure Switches
Actualizado: 2024-01-18
Explosion-Proof, UL & CSA Listed for Class I, Groups B, C & D and Class II, Groups E,F & G. The Series H2 Dual-Action Explosion-Proof Pressure Switch is designed for
sequencing two different actions as pressure of a liquid or gas increases or decreases.
The design consists of two concentric pistons operated by a single diaphragm with one
pressure chamber. Each piston actuates a separate switch independent of the other.
The switches may be adjusted to operate together, at opposite ends of the range or
at two intermediate set points. The threaded top is removed to field adjust or service
switches without disturbing electrical or pressure connections. The Duotect® switch
is explosion-proof and weatherproof. It can be mounted in any position and is not
affected by vibration.
