Device Overview
Introducing NCD’s IoT Industrial Wireless Absolute & Gauge Pressure and Temperature Sensor is the OEM piezo resistive pressure sensor with 316L stainless steel corrugated diaphragm and isolated oil-filling construction, boasting up to a 2 Mile range using a wireless mesh networking architecture. Incorporating a highly accurate Absolute & Gauge pressure sensor, transmits data at user-defined intervals. It measures Absolute & Gauge pressure and temperature with user configurable resolution at user defined intervals while sleeping during the time when it is not measuring or sending data.
Industrial Wireless Absolute & Gauge Pressure and Temperature Sensor is widely used for various liquid pressure measurement which is compatible with stainless steel and Viton®. The included sensor is rated for 0-100psi absolute pressure, 0-500psi gauge pressure sensor, 0-1000psi sealed gauge sensor with an accuracy of ±0.5%FS (pressure), and 0-5000psi sealed gauge sensor with an accuracy of ±0.5%FS (pressure) ±1.5℃ (Temperature). Easily interfaces using a standard 1/4″ NPT Male connection.

Status LED
The Status LED is used to indicate errors or other sensor diagnostics.
LED blinks once – Message was sent successfully and no error in last sensor read as well in data transmission.
LED blinks twice and then one more time – Message was sent successfully but there was an error in last sensor read.
LED blinks thrice – MCU is having issue communicating with the radio module.

Power Requirements and Expected Battery Life
Power Requirements
This Sensor has two power options:
- Powered by AA batteries (NCD recommends Energizer L91 batteries)
- External power supply (5-12 V DC) Current Requirement 250 mA
While changing the batteries:
- Turn off the sensor
- Only use new L91 batteries
- Checkout the polarity marking on the battery holder and batteries
- Replace all six batteries with new L91 batteries. Do not mix old and new batteries
- Batteries should not be replaced in fire-risky areas
- Do NOT install rechargeable batteries
