Product Overview
MODBUS HAPS03It is a high-precision pressure transmitter with a range of 0-1MPa (0-10bar/0-145psi). It adopts a diffusion silicon pressure sensor chip and a stainless steel isolation diaphragm structure, with high accuracy and good stability. Standard threaded interface (G1/4 or M20 × 1.5), can be directly screwed into the pipeline pressure tap. Connect to Home Assistant or PLC to collect pressure data through RS485 Modbus RTU digital output or 4-20mA analog output.

HA Constant Pressure Water Supply Scheme
HAPS03 Installed on Water Supply Pipeline → Data Sent to HA via RS485 → Writing Automation in HA:
1. Water Valve Open → Pipeline Pressure Decrease → HA Monitor Pressure<Set Value → Increase Water Pump Inverter Frequency → Pressure Recovery
2. Water Valve Closed → Pressure Increase → HA Decreases Inverter Frequency → Pressure Stability
3. Pipeline pressure>continuous high pressure setting value → possible pipe burst → emergency pump stop+alarm
More applications
- Air compressor systemGas storage tank pressure monitoring, automatic start stop compressor
- HVAC (Heating, Ventilation, and Air Conditioning)Pressure monitoring of chilled water pipes and cooling water pipes
- hydraulic systemContinuous monitoring and recording of hydraulic station oil pressure
