Temperature measuring instrument GRYF 9401

dimensionsdigitalLED

The device can be used separately as an autonomous measuring and control unit with the possibility of transmitting the measured quantity or it can be set up using the RS485 digital communication line into measuring groups (up to 32 units) connected to the PC. In such an assembly, it is possible to perform on the PC visualization of the technological process, to transfer and archive the measured data, to control the technological process using the measured values, to transmit different levels of messages and alarms. Archived data can be further processed in a spreadsheet (data is stored in DBF files). In case of PC failure or communication, individual modules can switch to autonomous measurement and control mode. When using the RS485 line, the measured temperature can be transmitted next to the main measured value. The instrument is operated by four buttons on the front panel. Some functions may be protected against unauthorized interference in the menu (eg prohibition of setting of PI controller parameters, prohibition of calibration). The measured value is displayed with a 5-digit LED visible. Properties The devices are manufactured in separate modules in DIN rail version with dimensions 90 x 106 x 58 mm in basic IP40 protection and can be supplied separately or already installed in a plastic box with transparent door with IP65 protection. The instruments are equipped with basic measurement and temperature measurement, temperature compensation of the main measured value (if required), two outputs - adjustable switches. During production, the devices can be supplemented by internal data transfer modules and PI controller.
