Controller BS-7400 is an electronic thermal recorder in a self-contained box suitable for wall mounting, powered by mains adapter 9-12V.

It ensures continuous measuring, display and recording of temperature in two points. The recorded data is saved in programmable time intervals and is printed in complete save protocol containing the name of the facility, the name of the company, the serial number of the controller and the number of readings; the temperature readings recorded at a particular moment are presented in a table.

Two temperature pick-ups are connected to the display panel with cables of different length, specified by the client. The pick-ups are mounted at different points in the supervised room or one of them is chosen to be exterior. The maximum length of the cable for each pick-up is 30 metres. The temperature range of the system is from -40 to +90 °C.

The operations with the controller are made easier by using only 3 buttons on the panel. During recording the system does not require supervision and once adjusted does not lose data in case of power failure. If during record mode there has been power failure, the recording continues after restoring powering until reaching the desired number of readings. After the automatic or manual suspension of recording You can print several save protocols and their copy can be handed to the end client, who the goods have been meant for.

A portable printer in a self-contained box is connected to each display BS-7400. One printer can be used for printing of the protocols of several modules, connected with a common communication cable or placed in different facilities or warehouses. Instead of a mobile printer there can be included a module radio transmitter and the data can be sent to a stationary personal computer within 60 metres. By means of a supplementary USB coupling the data can be stored on a notebook as .TXT or .XLS file.
