Overview

HPTM480 Temperature-pressure transmitter uses a high-quality, highly stable pressure core as its sensing element to accurately measure the hydrostatic pressure of the liquid, which is proportional to the liquid level. This pressure is then converted into a standard 4-20mA signal output through signal conditioning circuitry, enabling the measurement of liquid depth. The probe incorporates a high-precision temperature sensing element, allowing simultaneous measurement of the liquid temperature. Additionally, the product features a 4-digit dual-row LED display that shows both liquid level and temperature values simultaneously.

Having undergone long-term aging and stability testing, the product demonstrates reliable and stable performance, making it suitable for harsh outdoor environments. It has wide applications in groundwater, rivers, lakes, seas, surface water tanks, and storage tanks.

Features

Simultaneous measurement of liquid level and temperature
Large LED screen display, simultaneously showing pressure and temperature
Standard analog signal output
Dual anti-condensation and anti-condensation technology
