The GRYF 9000 series measuring instruments are modular measuring instruments for industrial measurements.
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.
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.
Transmission module (output measurement) - output - analogue 0 – 20mA, 4 – 20mA
- digital RS 485
Control Module (PI Controller) - output - voltage 0 – 1V, 0 – 5V, 0 – 10V
pulse 0 – 110 impulse/min
Separate external modules can be supplied to the devices:
- Impedance converter for remote measurements of pH, mV, O2 design on DIN rail, measuring head or electrode body.
- Relay set 2 outputs (2x changeover contact)
- Separate current line for transmitting temperature readings 0 – 20mA , 4 – 20mA
