Panel Mount Electrical Contact Pressure Gauges

-- Steady & Reliable Manufacturer --

Product Overview

Our Panel Mount Electrical Contact Pressure Gauges combine the reliable local visual indication of a standard Bourdon gauge with the functionality of an integrated pressure switch. These gauges are essential for control systems where specific pressure thresholds must trigger external devices, such as alarms, pumps, or valves, without relying solely on a separate transmitter. Designed for easy integration into control panels, they offer a compact, dual-function solution for pressure monitoring and safety control.

Key Features

Combines local indication with electrical switching contacts.
Adjustable set points (limit contacts) for high or low pressure.
Designed for integration into control panels and cabinets.

Typical Use Cases

Pump Protection: Automatically shutting off a pump upon reaching a high-pressure limit.
Filtration Systems: Activating an alarm or maintenance light when differential pressure is too high.
Compressor Control: Starting or stopping a compressor based on tank pressure set points.
Safety Systems: Triggering emergency shutdown sequences.
OEM Machinery: Integrated control and visual status indication.

Competitive Benefits

Dual Functionality: Provides visual gauge reading and remote switching signal in one unit.
Simplified Wiring: Reduces the complexity and cost of installing separate switches and gauges.
Easy Set Point Adjustment: Contacts are easily adjusted externally via a key or knob on the glass face.
Durable Contacts: Magnetic assistance ensures clean, reliable switching operations, extending contact life.

Payment and Shipping Details

We require standard payment terms of T/T (Telegraphic Transfer) or L/C (Letter of Credit) for international bulk orders. Shipping terms are typically FOB (Free On Board) Shanghai. Due to the electrical component integration, the lead time is approximately 15-20 days. Each gauge is individually tested for switching reliability before packaging.

Frequently Asked Questions

Q: Can the contacts be set for both high and low pressure limits?
A: Yes, we offer models with dual contacts (H-L or H-H) allowing the user to set both a high-pressure shut-off point and a low-pressure start/alarm point.

Q: Do these gauges require an external relay?
A: While the contacts can handle modest electrical loads, we strongly recommend using an external relay or contactor to handle the main power load of large pumps or motors, thereby protecting the gauge's internal contacts.

Q: What is the minimum pressure differential required for reliable switching?
A: To ensure reliable operation and avoid 'chattering,' the contacts should be set with adequate hysteresis (switching differential) appropriate for the specific application.
