Multi-I/O, Multi-Purpose

The OleumTech® GP-AP81 is a secure, rugged, and reliable General Purpose Wireless Transmitter designed for industrial process monitoring and control applications. It features two high resolution analog inputs (24-bit ADC) and two discrete programmable channels that can be configured for inputs or outputs in any combination. The discrete inputs can also be used as pulse counters (up to 2 KHz).

Industrially Hardened

The OleumTech Wireless Transmitters originated from the toughest outdoor oil and gas production locations throughout the world. They are designed to thrive in harsh, extreme weather conditions. Only the highest grade materials go in to building our wireless instruments. The AP81 is backed by a 2-year warranty.

Deploy Anywhere

This low-power wireless analog sensor transmitter can be powered using external power or optional battery pack providing extreme deployment flexibility. When powered by a battery pack, the GP-AP81 can operate for up to 10 years before needing a battery replacement.

Scalable Solution, Easy to Use

The GP Wireless Sensor Network is comprised of a Wireless Gateway and Wireless Transmitters forming a star or point-to-multipoint network structure. Adding additional Transmitters and managing I/O points are extremely simple with the OleumTech GP Network Configuration Software for PC is offered for free to its users.
