This manual introduces the function and theory of Geotech's submersible pressure transducer, including installation, operation, maintenance, troubleshooting, specifications, and replacement parts.
This manual provides detailed instructions for installing and operating Geotech’s submersible pressure transducer, including system descriptions, installation procedures, operation guidelines, maintenance, troubleshooting, and specifications. It covers various sensor types — vented gauge, absolute, and sealed gauge — and their applications. The transducer supports 4-20 mA analog and MODBUS RS-485 digital outputs, with optional lightning protection. Installation considerations include cable length, desiccant or bellows use for vented cables, and power supply requirements.
The manual also includes system specifications such as pressure ranges, accuracy, and communication protocols, along with troubleshooting tips and replacement parts information. It is intended for users installing the transducer in liquid environments compatible with 316 stainless steel, including wells, mineshafts, and industrial applications.
