HOBOnet Pulse Input - Contact Closure Sensor
$265.00 USD
A HOBOnet wireless pulse input sensor that connects to sensors with a pulse output; compatible with contact closures.
Important Information
Compatible with contact closures, such as tipping-bucket rain gauges or reed switches. A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor, OR one HOBO MicroRX Station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.
Overview
A wireless pulse input sensor that connects to sensors with pulse output. This sensor is compatible with contact closures, such as tipping-bucket rain gauges or reed switches. HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station, or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud software platform.

0 - 50 AMP Split-core AC Current Transformer Sensor
The Magnelab AC Current 0-50 Amp AC Current Transformer or CT (Magnelab part # SCT-0750-050) is mounted around a current carrying wire to measure AC Amperage. This CT provides 333mV output proportional to current and is used with the FlexSmart TRMS Module for True RMS measurement of sinusoidal and non-sinusoidal waveforms. The result is accurate current measurement for many types of equipment, including variable frequency drives and switched power sources.The Magnelab AC Current 0-50 Amp AC Current Transformer or CT (Magnelab part # SCT-0750-050) is mounted around a current carrying wire to measure AC Amperage
