Midtronics' battery monitoring solution

June 2009 Data Acquisition & Telemetry

Comtest is pleased to present Midtronics new Cellguard System and Cellguard Trace, a battery monitoring solution designed for simple expansion and worldwide accessibility. Midtronics Cellguard System combines the latest wireless communications technology with patented, field-proven battery conductance testing for thorough stationary battery health analysis.

Midtronics Cellguard System features:

* Continuous 24/7 online monitoring for system integrity assurance.

* Full conductance, battery voltage and temperature monitoring for battery state of health analysis.

* Wireless communications architecture ensures proper installation, easy operation and low maintenance costs.

* Inter-cell connection integrity monitoring ensures system effectiveness.

* Test signal to an individual cell or mono-block enables high resolution of system state of health.

* Web-enabled communications for remote surveillance.

* Advanced notification of battery problems via e-mail or text massage.

The Cellguard System has an operating temperature of 0 to +65°C and a storage temperature of –10 to +80°C. Its protection features include a sensor (2 and 12 V), fused test load and power paths, and PolySwitch protection for high heat detection.

Midtronics Cellguard Trace (UBM-1048) system provides effective string battery monitoring for 24 V or 48 V battery applications. Its easy-to-install Kelvin connection enables the Cellguard Trace to measure individual 12 V jar conductance, voltage and temperature every 24 hours, and warns or alarms when any measured parameter crosses a preset threshold. This provides early warning of battery degradation enabling individual jars to be removed from the string prior to full string degradation or system failure.

The system is designed to monitor stationary batteries in a variety of applications, including: telecommunications, wireless, fire and security alarms and control systems.
