Single channel Datalogger for Vibrating Wire Sensors

Model ESCL-12VT Overview

Model ESCL-12VT single channel datalogger is designed for collecting data automatically from any vibrating wire sensor with integral thermistor. With telemetry option, it transfers the data to cloud/private server through in-built GPRS/GSM modem at set intervals. Schedule can be set as fast as 5 minutes. Automatic collection and wireless transmission of data helps in reducing field costs and provides easy access to near real-time data with early alarms.

The datalogger has the facility of two way communication. This further reduces field costs significantly as it provides remote access to configure, receive system status update, and carry out maintenance or diagnostics and preventive actions from office itself. This eliminates any need of site visit after installation. 

ESCL-12VT is a compact rugged datalogger that can be used in a variety of application to provide accurate and reliable data from vibrating wire sensors. It features a wide operating temperature range, dependable standalone operation, low power consumption, compatibility with many telecommunication options and flexibility to support a variety of measurement and control applications. It has an on board 5-pin connector for rapid sensor connection. The durable construction makes it well-suited for unattended applications.
