A Piston Type Differential Pressure Gauge is used to measure the difference between two process pressures directly on a mechanical dial.
Parameter Typical Specification
Type Differential Pressure Gauge – Piston Type
Measuring Principle Magnetic/mechanical piston movement
Connection 1/4', 1/2' BSP / NPT, as required
Process Connection High Pressure (HP) & Low Pressure (LP)
Dial Size 100 mm / 115 mm / 150 mm
Differential Range 0–0.6 to 0–10 bar DP, as required
Static Pressure Up to 10 / 16 / 25 bar, depending on model
Accuracy Typically ±2% FSD
Wetted Material SS 316 / SS 304
Body Material SS 304 / Aluminium, as required
Piston Material SS 316 / suitable alloy
Seal Material NBR / Viton (FKM) / EPDM
Dial Aluminium, white background with black markings
Pointer Aluminium / black finish
Window Toughened glass / acrylic
Mounting Direct / surface / panel mounting
Overpressure Protection Suitable for specified static pressure
Operating Temperature Approx. −20 to +80 °C
Ingress Protection IP54 / IP65, depending on construction
Scale Differential pressure scale in bar / kg/cm² / kPa
Application Filter monitoring, pump systems, flow measurement, process lines, liquid/gas service Typical purchase specification:
Piston Type Differential Pressure Gauge, 100 mm dial, SS304/SS316 construction, 1/2' BSP(M) HP & LP connections, DP range 0–1 bar, static pressure 10 bar, accuracy ±2% FSD, IP65, with suitable seals and mounting arrangement.
If you give me the DP range, connection size, dial size, and static pressure, I can prepare a complete tender/quotation specification in a standard technical format.
