1. Do you supply hydraulic pressure switches in the UAE?
Yes. Mega Industrial Equipments supplies hydraulic pressure switches across the UAE as part of our hydraulic instrumentation range, alongside oil level and oil temperature indicators.
2. What types of hydraulic pressure switches do you supply?
Electromechanical pressure switches, electronic pressure switches, pneumatic pressure switches, and pressure transmitters.
3. What working temperature range do your hydraulic pressure switches support?
-25°C to +85°C.
4. What is the switching frequency of your hydraulic pressure switches?
90 cycles per minute.
5. How is the setting point adjusted on a hydraulic pressure switch?
The setting point is adjustable through a central screw.
6. How accurate are your hydraulic pressure switches?
Switching accuracy is ±5% of the end of scale at 20°C.
7. What is the hysteresis value on your hydraulic pressure switches?
It varies by execution type: approximately 10% of end of scale for membrane execution, 20% for piston execution, and 25% for Y execution, all measured at 20°C.
8. What is the mechanical life of your hydraulic pressure switches?
1,000,000 (10⁶) cycles at 70 bar (1,000 psi) at 20°C.
9. What electrical load can your hydraulic pressure switches handle?
A maximum load of 0.5A at 250V AC or 0.15A at 110V DC, with a simple normally open (NO) or normally closed (NC) contact configuration.
10. What's the difference between a membrane, piston, and Y execution pressure switch?
They differ mainly in hysteresis value, which affects switching precision — membrane execution offers the tightest hysteresis at around 10%, piston execution around 20%, and Y execution around 25%, all at 20°C.
11. What's the difference between a pressure switch and a pressure transmitter?
A pressure switch triggers an on/off electrical contact when a set pressure point is reached, while a pressure transmitter provides a continuous, proportional pressure reading rather than a single switching point.
12. Why is a hydraulic pressure switch important in a hydraulic system?
It monitors system pressure and triggers a safety response, alert, or shutdown when pressure moves outside a set range, helping prevent damage to pumps, valves, and other components from over- or under-pressure conditions.
