Description

The data logger has the capacity to acquire measurements from a variety of sensors and transmit them via GPRS. Data is transmitted to Detectronic’s cloud-based data portal which is well equipped with a powerful suite of online data collection, monitoring, analysis and reporting tools.

 

GPRS MODEM QUAD BAND

900MHz, 1800 MHz / 850MHz, 1900MHz – integral antenna.

CLOCK

Crystal controlled calendar clock with leap year adjustment.

Accuracy: 100 seconds per month maximum error over operating temperature range.

Synchronisation: option to synchronise clock to GSM network for greater accuracy.

RECORDING

Logging interval: programmable between 1 second and 1 hour.

Data storage: rotating store or store until full.

ENVIRONMENTAL

Operating ambient temperature: -20°C to +50°C.

Protection classification: IP68

(submersion at 1m depth for > 24 hours).

LOCAL SERIAL PORT

Full duplex, asynchronous.

Data rate: 1200, 2400, 4800, 9600 bps diagnostics.

SUPPLY

Internally powered by a user-replaceable lithium cell (internal back up cell maintains logging and local communications when main battery pack is discharged).

Typical battery life: >5 years, depending on mode of use.

ALARM DIAL-OUT

High/low threshold alarms with option to update data on alarm and more frequently thereafter.

Optional profile alarms can be set when sufficient historical data is available.

CONNECTORS

Military specification, compatible with MIL-C-26482.

WIRING OPTIONS

Direct cable or optional 8-channel interface for simpler and easier connection.

For transducer power control and alarm signalling (0 and 3 volt levels,

DIGITAL OUTPUTS

Active low, 100k output impedance).

1 FIXED OUTPUT

For ‘open collector’ signal bias (3 volts, 33k output impedance).
