Wigam - Pressure Gauge Ø80 Class 1 Oil Bath ML80/18C4S/A6/K1 - 07113019

Wigam ML80/18C4S/A6/K1 Pressure Gauge - Technical Specifications

The Wigam ML80/18C4S/A6/K1 pressure gauge is a pressure measuring instrument designed for industrial applications that require precision and reliability. This model features an 80-millimeter diameter and belongs to precision class 1, ensuring accurate measurements according to international standards. The oil-filled configuration protects internal components from vibrations and pressure fluctuations, extending the instrument's operational life.

Construction Features

The pressure gauge is equipped with a Bourdon tube measuring system, a sensitive element that allows for the detection of pressure variations with high sensitivity. The graduated scale is clearly legible and positioned on a large-diameter dial, facilitating reading even from a distance. The stainless steel or corrosion-resistant material housing ensures durability in harsh environments. The internal oil bath acts as a natural dampener, reducing mechanical wear caused by pulsating pressures or water hammer.

Practical Applications

• Heating and air conditioning systems for water pressure monitoring
• Industrial hydraulic systems and metalworking machinery
• Pneumatic systems and air compressors for operating pressure control
• Cooling circuits in production processes and chemical plants
• Gas and steam distribution systems in industrial settings
• Pressure control in centrifugal and volumetric pumps
• Monitoring of high-pressure fluid transport lines

Advantages of Precision Class 1

Precision class 1 indicates a maximum permissible error of 1% of the full scale, ensuring reliable measurements for critical applications. This level of precision is suitable for process controls, calibration of safety systems, and continuous monitoring of operational parameters. Compliance with international standards ensures compatibility with industrial control and automation systems.

Protection and Durability

The oil-filled system is a construction solution that protects the internal mechanism from external agents, humidity, and contaminants. This configuration is particularly advantageous in environments with frequent vibrations, where traditional pressure gauges might experience accelerated damage. The oil used is selected to ensure thermal stability and compatibility with the instrument's internal materials.

Installation and Maintenance

The Wigam ML80/18C4S/A6/K1 pressure gauge is designed for simple installation on control panels or directly on piping using standardized fittings. Routine maintenance is minimal, limited to periodic visual checks of the dial's condition and the protective glass's transparency. In case of calibration needs, it is advisable to contact specialized laboratories equipped with certified test benches.

Regulatory Compliance

The pressure gauge complies with European directives on the safety of measuring devices and international technical regulations. CE marking and the accompanying technical documentation certify compliance with quality and safety requirements. This compliance is essential for use in systems subject to inspection and control by certification bodies.

Full Scale Selection

Selecting the appropriate full scale is fundamental to ensuring accurate measurements and instrument durability. The full scale should be chosen so that the normal operating pressure is between 50 and 80% of the maximum scale. This practice allows for leveraging the pressure gauge's maximum precision zone and protecting the mechanism from accidental overloads.

Compatibility with Control Systems

Although the ML80/18C4S/A6/K1 model is an analog mechanical pressure gauge, it can be integrated into modern control systems by adding electronic pressure transducers in parallel. This configuration allows for maintaining a direct visual reading while also ensuring data acquisition for SCADA and industrial automation systems.
