Home » Hydraulic Pressure Sensors & Switches

Hydraulic equipment needs reliable pressure monitoring to keep systems running safely and efficiently. Pressure switches and pressure transducers help operators and equipment manufacturers protect critical components, prevent unexpected downtime, and maintain consistent system performance. Built for tough environments, these products are designed to handle the challenges found in mobile and industrial hydraulic applications, including vibration, pressure spikes, and demanding operating conditions.
From construction machinery and agricultural equipment to industrial machines and hydraulic power systems, choosing the right pressure sensing solution can make a big difference in equipment reliability and service life. SUCO ESI North America offers dependable hydraulic pressure switches and pressure sensors backed by decades of experience, engineering expertise, and customer support. We work closely with OEMs, distributors, and system designers.
Our hydraulic pressure switches and transducers are designed to withstand:
What is a hydraulic pressure switch?
A hydraulic pressure switch monitors system pressure and activates or deactivates an electrical circuit when a preset pressure is reached.
What is the difference between a pressure switch and a pressure transducer?
A pressure switch provides an on/off signal, while a pressure transducer continuously measures pressure and sends data to a controller.
Where are SUCO hydraulic products used?
Our products are used in construction equipment, agriculture, manufacturing, material handling, industrial automation, and mobile hydraulic systems.
