Description

The WIKA 736.51.160 differential pressure gauge is purpose-engineered for sensitive pressure monitoring in clean and demanding environments. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated. For the version with switch contact, magnetic snap-action contacts, reed switches, and electronic contacts are available. For triggering programmable logic controllers (PLC), electronic contacts and reed switches can be used, Operating within a 0...6 mbar range, with a secondary kPa scale, it ensures clarity and precision. Equipped with capsule technology, this instrument supports fine differential readings and incorporates a magnetic snap-action contact (series 821) for alarm triggering. The red RAL 3020 inner scale enhances visibility, while the electrical plug side connection and 2 x 1/2" NPT male ports simplify installation. Overpressure safety to 200 mbar and traceability via serial number with QR code make this gauge a dependable choice for lab-grade filtration, gas handling, and pressure-critical applications.

Special Features

• Differential pressure measuring ranges from 0 … 2.5 mbar

• Ingress protection IP66

• Case and wetted parts from stainless steel

• Version with switch contact for PLC applications

Applications

• Differential pressure measurement at measuring locations with very low differential pressures, for transparent, gaseous, dry, clean, oil- and grease-free media, also in aggressive environments

• Media chamber also suitable for corrosive media

• Process industry: Chemical industry, petrochemical industry, on/offshore

• Filter monitoring in ventilation and heating systems or in overpressure and clean rooms

• Differential pressure controlled monitoring of ventilator and blast pressures
