Pressure gauges, switches and sensors
We are a Pakkens distributor for pressure gauges, thermometers and gauge accessories; pressure switches, transmitters, level and flow devices are sourced from different manufacturers according to the application. We select the right range and type with you, based on the operating pressure and the environment of the system.
Measure, monitor, control
In a hydraulic or pneumatic system four quantities describe its health: pressure, temperature, level and flow. Pressure gauges and thermometers display them; switches, thermostats and transmitters act on the measured value by stopping the pump, starting the cooler or sending a signal to the PLC. Displaying makes a fault visible, controlling prevents it.
On the power units we build, we select these devices ourselves and test the unit by reading from them; in service and repair work we also look for the cause of a fault by measuring. As a Pakkens distributor we supply pressure gauges from stock, and we select the other devices with you according to the operating pressure, the environment and the signal requirement of the system.
The types, selection logic and frequently asked questions of each group are on its own page:

Product groups
Each group has its own page with types and a selection guide; sizes and manufacturer part numbers of the pressure gauges and coils in stock are in our catalog.
- Pressure gauges and vacuum gauges →Bourdon tube, glycerine filled, diaphragm, electric contact and digital pressure gauges, vacuum gauges and compound gauges: dial sizes from Ø40 to Ø100, ranges from 0-1 bar to 0-600 bar.
- Pressure switches and pressure transmitters →Mechanical and electronic pressure switches, pressure transmitters and transducers: components that measure pressure, switch at a set value or send a signal to the PLC.
- Thermometers, thermostats and temperature sensors →Bimetal and capillary thermometers, thermowells, thermostats and temperature sensors: components that show and control tank, oil line and process temperature.
- Level gauges and level switches →Sight glass level gauges with or without thermometer, float level switches and electronic level switches: components that show and monitor the fluid level in the tank.
- Flow measurement and control →Flow meters, flow indicators and flow switches: components that measure or show the amount of fluid passing through the line, or signal when the flow stops.
- Gauge isolator valves and pressure test equipment →Gauge isolator valves, push button gauge isolators, syphons, snubbers, test point couplings and test hoses: the accessories that connect a pressure gauge to the line safely.
- Solenoid coils →Replacement solenoid coils and connectors for hydraulic and pneumatic valves: 12 and 24 V DC, 110 and 220 V AC.
In our own manufacturing
A glycerine-filled pressure gauge is standard equipment on the hydraulic power units we build; the operating pressure is read from this gauge while the unit is tested. Pressure gauges and temperature indicators are also checked during unit overhaul and periodic maintenance.
