W0741 WiFi temperature sensor for connecting 4 external Pt1000 COMET sensors

Description

W0741 WiFi Temperature sensor for connecting 4 external Pt1000 sensors (probes).

Communication with the sensor is via a WiFi wireless network. The device allows you to send the measured values to the COMET Cloud or COMET Database online data storage within a minimum interval of 5 minutes. The values can be displayed on integrated web pages, or transmitted to third-party systems using the ModbusTCP protocol. The measured values are displayed on the LCD – monitoring.

The device continuously evaluates the alarm limits of the measured values and can send an email, alert with an acoustic or optical alarm if they are exceeded. Two alarm limits are enabled for each measurement channel.

The main advantage of the W0741 sensors with WiFi interface is the ease of use where WiFi infrastructure is already available. Place the sensor in the desired location and connect it to your WiFi network. A WiFi sensor in combination with COMET Cloud or COMET Database offers a complete monitoring and alarm solution without the need for server-based solutions. If required, you can also connect the sensor to a third-party system, either via ModbusTCP or by sending JSON data to an http server.

Thanks to these unique features, the WiFi sensor will cover all applications and a wide range of application areas.

An A1879 adapter is available for purchase for the power supply.
