Overview
The HPM280 smart pressure transmitter combines pressure measurement, local indication and a standard remote output in one field-mounted instrument. It uses a diffused silicon piezoresistive sensing element with signal conditioning, automatic testing and laser trimming for temperature compensation.
An integrated LCD allows operators to read process pressure at the installation point, while the selected analog or HART-enabled output sends the measurement to a PLC, DCS, recorder or other control equipment. The aluminum-alloy electronics housing is rated IP65 and includes an M20 × 1.5 cable gland for protected field wiring.
The transmitter can be configured for gauge or absolute pressure. Available output options include 4–20 mA, 4–20 mA with HART, 0–5 V and 0–10 V. Pressure range, reference type, output, accuracy, process connection and wetted material must be specified for each order.
Features
Aluminum alloy electronic shell with IP65 protection grade.
On-site display with simultaneous output of 4 ~ 20mADC and other remote signals.
Reverse polarity protection and instant over-current and over-voltage protection measures.
Adjustable zero point and full scale.
Strong anti-interference capability and excellent long-term stability.

Industrial Applications
The HPM280 is intended for local and remote pressure monitoring in general industrial systems, including:
Pressure monitoring in manufacturing
Metalworking
Chemical
Electrical
Various industrial operations
Installation and Commissioning
Mechanical Installation
Depressurize the line before installing or removing the transmitter. Inspect the port, seal and threads, then mount the transmitter vertically where practical.
Keep the instrument away from strong vibration and direct heat. Where vibration cannot be avoided, use a suitable bracket, impulse line or remote connection approved for the pressure service.
Wiring Check
Confirm the output version before wiring. A two-wire current loop and a three-wire voltage output do not use the same terminal arrangement.
Verify polarity, supply voltage and controller input, then close the enclosure and tighten the cable gland before applying pressure.
Zero and Span Verification
Check zero under the correct reference condition before commissioning. Apply known pressure points across the range and compare the local display, electrical output and reference instrument.
If adjustment is required, record the as-found and as-left results. Zero or span adjustment does not replace a complete calibration when traceability is required.
Final System Check
Inspect the installation for leakage, stable wiring and readable display orientation. Confirm the PLC or DCS scaling against the transmitter range.
Test alarms and interlocks through the control system where they form part of the application.
