Local Pressure Indication with Integrated Switching Control
WIKA contact pressure gauges combine accurate local pressure indication with electrical switching capability, allowing operators to visually monitor pressure while simultaneously controlling alarms, pumps, or other system components.
Available through Valin, WIKA contact pressure gauges are designed for industrial environments where reliable pressure monitoring and automatic response are required—without adding separate pressure switches or transmitters.
Why WIKA?
Why Choose WIKA Contact Pressure Gauges
WIKA contact pressure gauges are mechanical pressure gauges equipped with electrical contacts that activate when a defined pressure value is reached. This dual-function design allows a single instrument to provide both visual indication and control signaling.
Typical functions include:
- Switching alarms at minimum or maximum pressure
- Starting or stopping pumps and compressors
- Providing local pressure indication for operators
- Supporting safety and control functions in process systems
WIKA offers contact pressure gauges in multiple configurations, including dry and liquid-filled versions, to support a wide range of industrial applications.
Features
WIKA contact pressure gauges are engineered for reliable switching performance and long-term stability, even in challenging operating conditions.
Key advantages include:
- Precise switching accuracy paired with clear, easy-to-read pressure indication
- Multiple contact types, including magnetic snap-action and inductive contacts
- Adjustable set points, allowing flexible control thresholds
- Robust construction designed to withstand vibration, pressure fluctuations, and harsh environments
- Compatibility with control systems, including PLCs and alarm circuits
This combination of mechanical durability and electrical functionality helps reduce system complexity and improve reliability.
Applications
WIKA contact pressure gauges are commonly used in systems where local pressure visibility and automatic switching are both required.
Typical applications include:
- Pump and compressor control
- Hydraulic and pneumatic systems
- Industrial automation and machine building
- Oil & gas and petrochemical facilities
- Water and wastewater treatment
- Power generation and utilities
By combining indication and switching in one device, WIKA contact pressure gauges help simplify installations and reduce component count.
Q & A
Contact Pressure Gauges Q & A
A WIKA contact pressure gauge is a mechanical pressure gauge with integrated electrical switching contacts. It provides real-time local pressure indication while triggering electrical signals when preset pressure limits are reached, enabling control or alarm functions.
A contact pressure gauge combines two functions: pressure indication and switching. A pressure switch provides only an electrical signal, while a contact pressure gauge allows operators to visually monitor pressure and activate control functions using one instrument.
WIKA contact pressure gauges are available with several contact options, including:
- Magnetic snap-action contacts for reliable switching
- Inductive contacts for wear-free operation and long service life
- These options allow compatibility with different control and safety requirements.
Yes. Many WIKA contact pressure gauges are designed for industrial conditions, including vibration and pressure pulsation. Liquid-filled models and rugged case designs help maintain readable indications and consistent switching performance.
Key selection factors include:
- Pressure range and accuracy requirements
- Required contact type and switching function
- Environmental conditions such as vibration, temperature, and moisture Electrical system compatibility
Valin specialists can help ensure the selected gauge meets both measurement and control requirements.
