Differential Pressure Gauges, Switches & Transmitters

Orange Research has built a reputation as a world-leading differential pressure gauge maker for more than fifty years in operation. Their gauges detect the pressure difference between two places in a system and display the resulting differential pressure on a single gauge dial. A magnetic movement permits simultaneous detection of both pressures without using mechanical seals while isolating the differential pressure gauge function from the pressure chamber. 

Unlike regular pressure gauges, different pressure gauges can show minor differential pressure values even at high line pressures. Orange Research offers differential pressure switches using reed switches or relays to initiate alarms, activate other equipment, or shut down a system, in addition to their differential pressure gauge options. Models include two switches when high and low limit control is required. 

Orange Research has created a line of differential pressure transmitters that can also provide data signals. Unique Hall effect sensors in the microprocessor-based devices translate the differential pressure gauges' natural magnetic movements into electric impulses. The DP gauge devices provide analog output for remote location monitoring after processing. Local station readout is always available because the traditional pointer-and-dial gauges are still operational. The user can choose between current and voltage outputs. 

Orange Research manufactures differential pressure gauges, switches, and transmitters to satisfy customer requirements as an innovative and industry-leading flow measurement and differential pressure gauge maker.

Industrial and OEM Pressure Switches by NOSHOK

A pressure switch is a device that detects the presence of fluid pressure. Pressure switches use various sensing elements such as diaphragms, bellows, bourdon tubes, or pistons. The movement of these sensors, caused by pressure fluctuation, is transferred to a set of electrical contacts to open or close a circuit.

When selecting pressure switches, you must consider several critical criteria:

• The electrical requirements (volts, amps, AC, or DC)
• The area classification (hazardous, non-hazardous, general-purpose, water-tight)
• The pressure sensing range
• The body materials exposed to ambient contaminants
• The wetted materials - parts exposed to the process media

Typical applications for mechanical pressure switches include hydraulics & pneumatics, pumps & compressors, tank monitoring, leak detection, and water management.

NOSHOK's new mechanical pressure switch program addresses a broader range of applications. It offers a significantly expanded selection of process and electrical connection options, including spade terminals, Hirschmann, Packard, Deutsch, M12 x 3-pin, flying leads, terminal screws, and both Weatherpack Tower and Weatherpack Shroud. Each of the four new NOSHOK switch series offers vacuum, low pressure, and high-pressure versions and is CE compliant for RFI, EMI, ESD suppression, and RoHS compliance.

The NOSHOK 100 Series Mechanical Compact SPST Pressure Switch has been updated with a creep action, low current switch. These switches have silver-plated contacts with switch adjustment ranges ranging from vacuum to 6,000 psi. The 100 Series switch series includes housing materials such as brass and zinc-nickel and wetted parts made of Buna-N or Kapton, depending on the model.

NOSHOK’s new 200 Series Mechanical Compact SPDT Pressure Switch is an SPST or SPDT snap-action switch with solid Silver contacts. This switch ranges from vacuum through 6,000 PSIG and Brass or Zinc-nickel housing material with Buna-N diaphragm wetted parts.

The new 300 Series Mechanical Compact SPDT with Adjustable Hysteresis Pressure Switch is an SPST or SPDT snap-action switch with solid Silver contacts. The 300 Series offers switch adjustment ranges from vacuum through 4,600 PSIG depending on model and a standard Zinc-nickel housing with Buna-N diaphragm wetted parts. The NOSHOK 300 Series switch provides an improved contact rating over the previous version of 6A 125V/250VAC and 6A 12/24VDC.

Lastly, NOSHOK’s new 400 Series Mechanical Heavy-Duty Pressure Switch is a snap-action, high current device that offers field adjustability. The 400 Series offers switch adjustment ranges from vacuum through 4,600 PSIG with a Standard Zinc-nickel with Buna-N diaphragm wetted parts. This switch also provides an improved contact rating over the previous version of 6A 125V/250VAC and 6A 12/24VDC.
