Receiver with Cloud capability  SRV250

Stream transmitter data anywhere via the mobile phone network, giving you real time access to the sensor outputs from anywhere you choose.

The SRV250  "pushes" data to the mobile network whenever a logging takes place. Provided the collection of the data has been setup at some location - either on a cloud server or on a physical PC connected to the internet - then data upload can take place. If the data collection point is unavailable, the SRV250 continues to log, storing data in its internal memory. When the data collection point is reconnected, the SRV250 automatically uploads all stored data and thereafter it returns to uploading data whenever a log takes place.

Compact single box solution:  
Built-in 3G,
250,000 readings fall back logging. 
24 hour back up battery should AC supply fail
Optimised data packet protocol providing cost effective use of SIM
GSM text messaging for channels in alarm
Use with any Eltek Darca software (Darca plus, Darca Heritage versions 1 or 2)
Supplied with free Gateway software.
Can also be connected to your network

The SRV250 provides huge flexibility for data gathering, please contact us to discuss your application, we can guide you through the process and offer suggestions for an effective implementation.

The Mini Squirrel
The first release of the GenII MS "Mini Squirrel" series is intended for RH, temperature and CO2 applications. 

The dataloggers are battery operated and ideal for short or long term environmental monitoring.

Mini Squirrel is ideal for monitoring smaller spaces such as galleries or laboratories. A feature of the Mini Squirrel is ease of deployment and data download. A top panel mounting jack socket is provided for data download.

The scrolling LCD display provides real time sensor values and screen prompts inform the user that the logger is set up and ready to go as required.

Eltek’s Darca Lite Windows software is designed for use with the MS Mini Squirrel, enabling the user to configure, download data, and graph historic data quickly and easily.

The Logmitter

The GenII Logmitter range is a series of devices launched by Eltek in 2017 that can be configured either as a conventional GenII transmitter or a a standalone datalogger.  

Eltek’s GenII Logmitter is a first in that you get a compact self-contained and highly accurate device that is a logger or a transmitter as required.

System Operation
Configured as a logger and deployed alone, it is ideal for smaller spaces and short term or temporary events in sites such as galleries or laboratories. For large buildings, e.g. city block museums, storage areas or research laboratories, it can be deployed as a transmitter with other Logmitters which are also configured in transmitter mode, reporting to a receiver.

Used together with Eltek Darca Heritage software, which is designed for conservators and collection managers alike, it provides the ideal solution for detailed environmental audits and day to day monitoring. Logmitter simply grows with your expanding requirements with all data available on a common platform.

Transmitter with backup memory

The GenII M series is a family of transmitters that incorporate standard GenII transmitter features plus backup memory, which safeguards data should a temporary interruption of the logging infrastructure occur. 
Designed to meet the data reliability targets for the pharmaceutical and laboratory sectors, the first release of the GenII M series includes models with inputs for thermistor, thermocouple, and PT100 sensors together with built-in RH and temperature and inputs for incubator monitoring applications.

System Operation
The GenII M series retains the standard GenII transmitter specification and adds 12,000 readings of built-in memory in continuous overwrite mode. This means many weeks of data can be held in the transmitter.
The logging interval is configurable, and is ideally set to be the same as the system logging interval. However the back up memory logging interval and therefore memory usage and granularity can be optimised depending on the user's requirements.
Data is downloaded using the TX download program and is saved to the PC in Windows CSV format. Each reading consists of the reading value and time stamp.
