Around-the-Clock Protection

The OleumTech® CP1 Cathodic Protection Transmitter Kit is designed to help monitor the integrity of a cathodic protection system by monitoring both current and voltage. The CP1 Transmitter provides its users the flexibility of selecting the Current Range: 0-20, 0-40, or 0-80 Amp. It also provides 0-50 Voltage DC input for monitoring cathodic rectifier DC Voltage output. The CP1 features high resolution 24-bit analog to digital conversion (ADC). The kit includes a DC Current Sensor. This ultra-low-power transmitter is powered by a replaceable battery pack that provides up to a 10-year life.

Reliable, Scalable, and Safe

The field-proven wireless sensor node communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network, creating a highly scalable network, accommodating virtually any I/O requirement.
