Overview
HPM5010 Intelligent pressure controller adopts high integration ARM and industrial grade MCU as the core and combines with high-accuracy AD converter and high-stability pressure sensor. It is carefully calibrated to ensure fast and accurate pressure measurement and switching action. Three large touch buttons with backlight and with display function design can make the field setting very conveniently. This product combines pressure switch, transmitter and display together and is equipped with two-way switch output (PNP or NPN), one-way analog output signal and one-way RS485 interface. It can be used to monitor pressure for liquid and gas. It is suitable for machinery manufacturing, machine tool system, hydraulic and pneumatic systems, pressure monitoring, pumps, compressors, and other general industrial fields.

One Device for Measurement and Control
Local Pressure Indication
The self-luminous OLED shows the measured pressure at the installation point. Operators can select psi, bar, mbar, Pa, kPa or MPa to match the plant standard. The display can also show ambient temperature, the analog output value and recorded minimum or maximum pressure values.
Two Switching Points
Two pressure control points can be specified for machine sequences, alarms or protection logic. Depending on the selected configuration, the transistor switching output is PNP or NPN. Each switch can be configured as normally open or normally closed.
The two red switch indicators provide a direct view of output status during setup and troubleshooting.
Continuous Signal Transmission
Where the controller also needs a continuous pressure value, the HPM5010 can be ordered with a current or voltage output. This allows the same measuring point to support local indication and remote monitoring without adding a separate transmitter.
Digital Communication
RS485 with Modbus communication is available for connection to compatible industrial control or data-acquisition systems. Network parameters, the register map and the exact output combination should be confirmed for the ordered version before PLC or SCADA programming begins.
PNP, NPN and Analog Output Options
Please match the selected output to the electrical input of your receiving controller. PNP and NPN are transistor switching formats; they are not interchangeable with an analog pressure signal.
PNP Switching Output
A PNP output sources the positive supply to the connected load when the output changes state. It is commonly selected for PLC input modules designed for sourcing sensors.
NPN Switching Output
An NPN output sinks current to the common or ground side. Select an NPN output when your PLC or controller input is designed for a sinking sensor. Confirm the input circuit and common arrangement instead of choosing by regional convention alone.
Voltage Output
We offer 0–5 V, 1–5 V, and 0–10 V output options for compatibility with various control inputs. Voltage signals are suitable for relatively short cable runs in controlled electrical environments. Please confirm the input impedance and common reference of your receiving device before selection.
Current Output
Current output options include 4–20 mA, while the technical table also references a configurable 0/4–20 mA format. Current transmission is useful when a continuous pressure value must be carried to a PLC, display or acquisition module. Confirm whether the ordered output is active or requires a particular wiring arrangement.
RS485 Modbus
RS485 provides digital communication for compatible Modbus networks. It can support centralized reading of pressure data where the system architecture favors digital communication. Please configure the communication settings, node address, cable specification, and termination according to the protocol documentation supplied with your HPM5010.
Programmable Pressure Switching
Normally Open or Normally Closed
Each switching point can be set for normally open or normally closed operation. The correct state depends on how the machine should react during normal pressure, an alarm and loss of power. Please define the required control logic before commissioning.
Hysteresis Mode
Hysteresis mode uses a switch point and a reset point. The separation between them helps prevent repeated output changes when pressure fluctuates close to the threshold. This mode suits pump start/stop control, compressor supervision and high- or low-pressure alarms.
Window Mode
Window mode evaluates whether pressure remains inside or outside a defined band. It can be used where the process must stay between minimum and maximum pressure limits rather than respond to one threshold only.
Adjustable Delay
The switch delay can be set from 0.00 to 1000.0 seconds. A suitable delay can prevent short pressure pulses from triggering an unwanted action. Delay settings should not be used to mask genuine pressure instability or an incorrectly sized measuring range.
OLED Display and Field Adjustment
The HPM5010 uses three touch keys with blue backlighting for field configuration. Chinese and English menu languages are available. The OLED display can be electronically rotated through 180 degrees, while the main body can rotate through 330 degrees to improve the viewing direction after installation.
This two-part adjustment is useful when the process connection fixes the sensor position but the operator needs the display to face an aisle or service area. Please rotate the display and body only within their permitted mechanical ranges, and do not use the housing as a lever when tightening the process connection.
The on-device interface allows technicians to review pressure, units, output status and configuration without opening a separate control panel. Access to settings should remain under the plant’s commissioning and change-control procedures.
Media and Material Selection
We design the HPM5010 for liquids and gases compatible with 304 stainless steel. Please assess compatibility with every wetted component, not only the outer housing.
We offer material configurations including 316L stainless steel, tantalum, Hastelloy, and titanium for different application requirements. These options are not automatically suitable for every corrosive medium, so please review the fluid concentration, operating temperature, cleaning chemicals, and seal requirements before selecting the material code.
We specify a medium temperature range of -30 to +80°C for the HPM5010. For hotter processes, you may need a suitable cooling element, impulse line, or high-temperature instrument to keep the sensor within its operating limits.
Industrial Applications
Hydraulic Equipment
The HPM5010 can monitor line, accumulator or actuator pressure and provide a switching signal when the process reaches a defined limit. Its analog or RS485 option can send the measured value to the control system for trending or process supervision.
Pneumatic Systems
In compressed-air equipment, the two switch points can be assigned to low- and high-pressure conditions. The selected measuring range should suit the normal working band and expected pressure peaks.
Pumps and Compressors
The switch can provide pressure-dependent control or alarm signals in pump and compressor systems. The external control circuit must be designed around the output current limit; motors and other high-current loads normally require an interposing relay or contactor.
Machine Tools and Manufacturing Equipment
The compact display and programmable outputs support pressure checks in lubrication, clamping, cooling and other auxiliary circuits. Window mode can help verify that the machine pressure remains within an approved operating band.
Hydropower, Energy and Chemical Systems
The product can be considered for compatible utility and process media in hydropower, energy and chemical installations. Material compatibility, temperature, electrical classification and required approvals must be checked against the actual site conditions.
