Temperature meter


The Pulsar temperature meter is designed to measure temperature through one or two channels.

The temperature meter includes a calculator and one or two platinum resistance thermocouples. The principle of operation of the device consists in measuring the temperature by processing the measurement results with a calculator.

The device measures, calculates and displays the following parameters on the LCD:

  • temperature, (ºС); temperature difference, (ºС); date and time; network address; error codes.

The meter has a nonvolatile memory in which temperature values ​​are recorded over a time interval. The depth of the archive is 60 months, 184 days and 1488 hours. Using the M-Bus protocol, it is possible to read a monthly archive with a depth of 24 entries. The non-volatile memory stores an event log containing information about errors that occur during operation and changes in tuning parameters.

The meters are supplied both without interfaces and with interfaces: RS485, M-Bus, radio channel. The choice of the interface is made when ordering the device.
