Type 711.12 manometers

Differential pressure indicator with baffle plate – two independent measuring systems.

Data sheet

Product information

The model 711.12 differential pressure gauge is designed for the simultaneous display of two pressures and the resulting differential pressure. It is based on two independently operating bourdon tube measuring systems and is suitable for gaseous and liquid, non-aggressive media. Typical applications are in heating, air conditioning and ventilation technology as well as in industrial systems.

Special features

  • Nominal sizes: 100 mm, 160 mm
  • Display ranges: 0 to 0.6 / 0 to 1,000 bar
  • Accuracy class: 1.6
  • Two process connections (G ½ B) and two independent pointers
  • Differential pressure indicator with staggered disk (±50 % of full scale value)
  • Body: stainless steel, painted black
  • Wetted parts:
    Copper alloy (<100 bar),
    CrNi steel (≥100 bar)
  • Protection class: IP33
  • Temperature range:
    Environment -20 to +60 °C,
    Medium up to +60 °C (soft soldering) / +100 °C (hard soldering)

Advantages

  • Simultaneous display of two pressures and differential pressure
  • Robust design for HVAC applications
  • Optional versions for aggressive media (type 731.12)
  • Variants with liquid filling for dynamic loads (type 713.12)

Variants

Manometers in plant engineering and valve modification

Manometers are indispensable components for pressure monitoring in complex systems. They are used in numerous applications – from differential pressure measurements on basket strainers for filter condition monitoring, pipe production and pressure testing to integration in SKID systems for chemical, energy and water technology. Manometers and the right accessories such as globe valves, siphons and pressure surge reducers are also crucial for operational safety and compliance with standards in valve construction and modifications.

Typical areas of application:

  • Basket strainer: Differential pressure indicator for early detection of soiling
  • Pipe production: Pressure testing and monitoring during assembly
  • SKID systems: Integration in valve stations and dosing systems for process control
  • Valve construction: retrofitting manometers and accessories for modifications
