The Fantinelli firm was founded in Milan in 1878 by Diomiro Fantinelli, who was the first in Italy to produce pressure gauges. The firm was first moved to Busto Arsizio in 1921 land then, in 1990, established in Solbiate Olona.
Fantinelli family has always owned the firm and has managed it for four generations. Now the fifth one is present to continue its traditions.
In 1938 Adelio Fantinelli patented a “compensated metallic expansion pyrometer“ that enriched the already large products range.
The present-day Fantinelli S.r.l. boasts a range of products about traditional or special instruments and devices dealing with Pressure and Temperature Measurement to meet specific requirements.
Our production organization is based on technologies and plants fit to achieve a High Level quality, guaranteed by our Quality Manual in accordance with ISO 9001:2000.
PRESSURE GAUGES
1.1 Bourdon Tube Pressure Gauges
- stainless steel tube or Monel;
- watertight casing, dry or liquid filled execution;
- NS 100 – 150 – 200 – 260;
- ranges included between -1 and 1600 bar.
Instruments of SP 300 series are designed for special executions; with dial NS 100 and 150 are the base for the electric contact pressure gauges.
1.2 Standard Bourdon Tube Pressure Gauges
- copper alloy pressure element assembly;
- DN 40 – 50 – 63 – 80 – 100;
- ranges included between -1 and 400 bar.
1.3 Square Casing Pressure Gauges
- stainless steel C-Bourdon tube pressure element;
- NS 96×96 – 144×144;
- ranges included between -1 and 600 bar.
1.4 Bourdon Tube Pressure Gauges for General Purpose
- watertight casing, dry or liquid filled execution;
- NS 40 – 50 – 63 – 80 – 100;
- ranges included between 1 and 600 bar.
These instruments are manufactured for all those industry’s sectors which require highest quality pressure gauges with stainless steel casing.
DIFFERENTIAL PRESSURE GAUGES
Independent Diaphragm Differential Pressure Gauges
DP 360
- ranges included between 100 mbar and 25 bar;
- static pressure 100 bar;
- scale angle 270°;
- accuracy class 1,6.
DP 460
- ranges included between 25 and 100 mbar;
- static pressure 25 bar;
- scale angle 270°;
- accuracy class 1,6.
Glass Tube Differential Pressure Gauges
- casing in profiled steel sheet or wood;
- ranges included between 100 and 1500 mm.
Double C-Bourdon Tube Differential Pressure Gauges
- watertight casing for dry or liquid filled execution;
- NS 100;
- ranges included between 1 and 60 bar;
- accuracy class 1,6.
DIAPHRAGMS ABSOLUTE PRESSURE GAUGES
Diaphragms Absolute Pressure Gauges
- Watertight casing;
- NS 100 – 150;
- ranges included between 60 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
DIAPHRAGM PRESSURE GAUGES
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.
THERMOMETERS
Expansion Thermometers
- Inert gas filling;
- Sensitive bulb rigidly connected to the casing
- (local thermometers) or by capillary (distance
- Reading thermometers);
- NS 100 and 150 watertight casing;
- Indication ranges included between -80 and +600 °C.
Thermowells
- From pipe or bar stock;
- Threaded or flanged;
- AISI 316L st.st. or special materials.
Glass Thermometer
TV 424
- Painted Aluminium Watertight rectangular casing;
- Adjustable or rigid stem;
- Ranges included between -30 and +600 °C.
TV 426
- Anodized aluminium V-shaped casing;
- Rigid stem;
- Ranges included between -100 and +650 °C.
DIAPHRAGM SEALS FOR SPECIFIC APPLICATIONS
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.
