GSM Datalogger is designed to record from two external temperature probes and two two-state inputs. In case of exceeded set limits, SMS and JSON messages can be sent via GPRS data connection. Measured values can be sent to the internet storage COMET Cloud, which is complete monitoring, alarm, and analysis system.

It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD, and acoustically by built-in beeper. The recording is performed in non-volatile electronic memory.

The data can be transferred to a PC via included USB-C cable. GSM recorder includes a Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.

This model can measure up to two temperature values, which are sensed by outdoor Pt1000/0 series probes. In addition, it is provided with two binary inputs for monitoring voltage-signal changes or changes of a signal coming from a voltage-free contact. The binary input changes are registered immediately, irrespectively of the recording interval setting.

Connection Mode: For the procedure for connecting wires to the connecting block refer to Annex 4.

To safe record the input status, the signal must be present for at least 1 s. Binary inputs of this device are not able to capture connected/disconnected voltage status. Input signals are connected to a connecting block. The response to a temperature jump depends on the probe design. As a rule, this device is a few times faster than the inner-sensor model. The maximum length of the probe line wire should not exceed 15 m; the maximum length of the binary-input cable should not exceed 30 m. It is recommended to use shielded cables. The device’s ingress protection is IP 20. Due to low ingress protection, the device is not suitable for use in dusty rooms or rooms exposed to water ingress.
