Wiring of Hydraulic Electronic Pressure Controllers: Do Not Mix Up PNP and NPN
NP and NPN are the two most common transistor switching output types for hydraulic electronic pressure controllers. Many field technicians underestimate the difference between them and treat the two outputs as interchangeable, leading to no switching action, continuous energization of actuators, PLC input damage or even unexpected hydraulic movement during commissioning.
Digital Display on Hydraulic Electronic Pressure Controllers: What It Does and Whether the Price Premium Is Worth It
Electronic pressure controllers for hydraulic systems are available in two variants: models with local digital displays and basic versions without screens.
What Is the Proper Hysteresis Setting for Hydraulic Electronic Pressure Controllers
Hysteresis, also called dead band, is one of the most critical parameters when configuring electronic pressure controllers on hydraulic stations.
How to Adjust Setpoints on Hydraulic Electronic Pressure Controllers
Electronic pressure controllers are widely adopted on modern hydraulic stations for pressure cutoff, pump unloading and low-pressure alarm.
Hydraulic Electronic Pressure Controller vs Mechanical Type: When Should You Upgrade
Mechanical pressure switches have served hydraulic stations for decades for simple pressure limit and safety interlock tasks. However, as industrial hydraulic systems move toward precision control, data collection and automated monitoring, many users face the decision whether to replace legacy mechanical units with electronic pressure controllers.
Over-Tightening Mounting Torque for Pressure Sensors: Why Excessive Torque Damages the Diaphragm
During pressure sensor installation, technicians often apply excessive torque when threading sensors into manifolds or pipe ports, believing a tighter connection guarantees leak-free sealing.
Pressure Measurement of High-Temperature Hydraulic Oil: How to Read Temperature Limits from Pressure Sensor Datasheets
When measuring pressure for high-temperature hydraulic oil, many engineers mistakenly only check one temperature value from the datasheet, confusing medium temperature, ambient temperature and compensated temperature range.
Pressure Sensor Reading Drift: These Are the 5 Most Common Root Causes
eading drift is a frequent and frustrating failure mode for pressure sensors and transmitters across hydraulic, process and industrial automation systems. Drift manifests as slow, gradual offset changes in measured values, which cannot be eliminated by simple zero reset in many cases
How to Select Explosion-Proof Pressure Transmitters for Hydraulic Stations & Mandatory Installation Locations
Hydraulic stations using flammable hydraulic oil or deployed in hazardous process areas require careful evaluation of explosion-proof pressure transmitters.
