Solid front pressure gauges are manufactured as per EN 837-1 and ASME B40.1. During the design of this type of pressure gauges, “safety” factor is taken into great consideration. Safety is guaranteed by a protection baffle wall positioned between the pressure element assembly and the dial, and by a blow-out device made of a back plate which allows an eventual pressure vent from the casing.

Diaphragm seals

Diaphragm seal consists of an elastic element that insulates the process fluid from the sensing element, transmitting pressure through the compression of a liquid in a separation chamber.

It is necessary to adapt this device where there are particular physical and chemical characteristics incompatible with the sensing element. This way the instrument is no more subject to drawbacks caused by particularly aggressive fluids or by highly viscous, crystallizable or solidifiable process fluid.

Diaphragm pressure gauges

  • cwatertight casing;
  • NS 100 – 150;
  • ranges included between -16 mbar and 25 bar.

 

This instrument has a diaphragm that, under the process fluid pressure, acts directly on the movement. This type of instrument can detect the pressure of highly viscous or crystallizable or solidifiable fluids.

Diaphragms absolute pressure gauges

  • watertight casing;
  • NS 100 – 150;
  • ranges included between 25 mbar and 2,5 bar abs.

 

The absolute pressure gauges are employed for those applications that require to measure the pressure without depending from the fluctuations of the atmospheric pressure. This function is carried on with an vacuum chamber used as a reference.

Pressure gauges for low pressures generally used for gas

  • capsule pressure element;
  • copper-berillium or stainless steel capsule;
  • NS 63 – 100 – 150;
  • ranges included between -6 and 400 mbar.

Hydraulic comparison calibration pumps CP 328

The pumps CP 328 make it possible to generate hydraulic pressures up to 800 bar necessary for the comparison calibration of pressure gauges, pressure switches and transducers with standard gauges. Their sturdiness and compactness make them easy to use both in the work shop and in the field. Their installation and maintenance have been simplified as muche as possible so that they may be used immediately.

 

Hand Pumps

The CP type hand pumps are used for testing and calibration of a wide range of pressure devices, such as dial gauges, sensors and switches.

The hand pumps can be used as a stand alone device or in conjunction with reference standard instruments, for example, the digital pressure gauges.

 

Digital pressure gauge CP 332

CP 332 is a family of digital pressure gauges that grants important accuracy specification and can be used for both pressure measurement and pressure calibration on gauges, sensor and switches.

– NS 100 and 150 waterthight casing in dry or liquid filled execution;

– ranges included between –1 and 400 bar.

  • transmitter with 4 ÷ 20 mA output.

Electronic instrumentation

The operation of this instruments is based on the sensor deflection on which surface a resistance circuit is fixed. The deflection caused by process fluid pressure produces a resistances circuit unbalance, which due to such effect causes a variation of electrical signal proportional to the applied pressure.
