Product Overview
HRT-P50DH is a direct-reading downhole electronic pressure instrument. The downhole probe contains pressure and temperature sensing elements and sends the measured data to a surface display or data-processing unit through the cable, allowing continuous readings without retrieving the probe for each measurement.
Applications
Typical applications include oil wells, coal-bed methane wells, water-source wells, geothermal wells and other downhole pressure-and-temperature monitoring tasks.
Selection & Application
Selection should consider pressure range, installation depth, well-fluid compatibility, temperature, probe diameter, cable length and required output. The source manual lists 22 mm, 28 mm and 32 mm probe-diameter options and 300 mm, 350 mm and 450 mm probe lengths.
Installation & Integration
The probe and cable should be assembled and sealed before running downhole. Protect the pressure port from mud or debris, protect the cable from impact and check the signal periodically during installation.
Configuration Options
Pressure range, probe diameter, probe length, cable length and 4–20 mA or RS485 interface can be selected for the project.
Next Step
For selection or quotation, please send the well type, installation depth, pressure and temperature range, fluid, required probe diameter and output.
