Mobeye ThermoGuard TwinLog CML4255 Temperature Alarm
The Mobeye ThermoGuard TwinLog CML4255 is an extremely accurate and user-friendly temperature monitor. As soon as the temperature deviates from the set limit values, you will receive an alarm message. In addition, it logs the temperature values at a self-selected interval and displays them in the online portal. The CML4255 has a reliable temperature sensor, with the option for a second one. The device is fully battery powered, or uses external power. The built-in communication module can connect to the 4G LTE-M and the 2G network.
The CML4255 measures, monitors and logs temperature values. If the temperature or one of the inputs indicate an alarm status, the CML4255 notifies you by app (IOS/Android), telephone call (voice message), text message and/or e-mail. The contact persons can be set, with multiple options for the alarm message.
The log functionality is available when using the Mobeye Internet Portal. The logged temperature values are sent to the portal periodically and after an alarm, for display in table and graph form.
The Mobeye ThermoGuard TwinLog CML4255 runs for more than a year on a set of batteries. When using an external power source (12-24V DC or mains), it also sends “power failure” notifications.
The temperature sensor is digital and extremely accurate. The minimum and/or maximum temperature limit is adjustable between -35 °C and +70 °C. The sensor is factory calibrated and indicates the value in decimals. The interval for logging the values and transferring them to the portal is adjustable.
One sensor is included in the standard product. A second sensor can be connected, which is available as an optional accessory.
In the event of an an alarm, the Mobeye ThermoGuard TwinLog sends alarm notifications by app (IOS/Android), telephone call (voice message), text message and/or e-mail. The message includes the actual temperature.
For the push messages there is a choice between an escalation plan or a group message. The escalation plan allows the recipient to acknowledge the push message, so that the other contacts no longer receive the message. If none of the recipients acknowledges the push message, a call is made. The number of contacts is unlimited.
CML4255: External voltage vs battery powered
The Mobeye ThermoGuard TwinLog can run on batteries for a long time and is therefore independent of an external power source. If an external power source is available, it is recommended to connect it. The availability of the power supply is then monitored. It will also send power failure alarms. In the event of a malfunction, a message will be sent. The batteries take over and the CML4255 continues to monitor and send alarm messages. A notification will be sent once power is restored.
Batteries are included. A country-specific mains adapter is available as accessory.
Alarm inputs, piezo siren and open collector output
In addition to the temperature sensor, the Mobeye ThermoGuard TwinLog CML4255 has two NO/NC inputs for connecting alarm contacts and sensors. These can be used to monitor the status of a make/break sensor or device, such as an air conditioner or door magnet. In the event of an alarm, an audible alarm indication may be triggered by the internal piezo siren. In addition, there is an (open collector) output to switch an external device.
How it Works
The Mobeye CML4255 continuously measures the temperature values and logs them periodically. This way you are fully aware of alarm situations and the complete temperature trend.
- Place the sensor in a place with a stable temperature, not too close to the heat sink or heat source.
- Set the temperature limits and log frequency and choose contacts for the notifications.
- If it gets too cold or too hot, the ThermoGuard TwinLog sends alarm messages to the contacts. The logged values can be viewed online in table and graph form.
