Digital Temperature Controllers

Product Details:

TR-101 digital temperature controller is used to measure and control device temperature via four independent sensors connected in a two or three-wire circuit, with subsequent indication of the temperature on the display. The device can be used in different industrial, utility and agricultural applications.

The device has the following functions:

• Measuring the temperature on four independent channels using standard sensors
• Regulating the temperature using the proportionate-integral-differential (PID) principle with an output key unit (relay)
• Two-level temperature regulation
• Displaying the currently measured temperature value on the integrated LED digital indicator (scanning)
• Transmitting the measured temperature values of the controlled sensors to a computer via built-in RS-485 Mod-bus RTU protocol
• Discovering line breakdown or faults in connected sensors
• Digital filtering and correcting of the temperature being measured
• Programming via the front panel buttons or a PC (free PC software)
• Saving the settings in case of power outage
• Protecting the settings against unauthorized changes (password protected)
• TR-101 can use any voltage between 24 and 260V AC, regardless of the polarity

Product Details:

??R-100?? is the microprocessor based device intended to measure and control temperature mode of dry-type transformer with four transducers connected by two or three wire circuit, with subsequently displaying the temperature on the display and sending alarms when any parameters are outside preset limits.

The product can also be used for protection of HV motors and generators.

The product has the universal power supply of 24 to 265 V (AC or DC) and connection to network EIA/TIA-485 with MODBUS RTU / ASCII protocol.

The product can be applied with the following types of temperature transducers:

– PT100 – platinum transducer with rated resistance of 100 Ohm, at 0°??;

– PT1000 – platinum transducer with rated resistance of 1000 Ohm, at 0°??;

– PT??1000 (EKS111) – transducer with rated resistance of 990 Ohm, at 25°??;

– PTC (minika) – cold resistance of transducer of 20-250 Ohm.

The structure of ??R-100?? is made in plastic housing designed for mounting on the front panel of the board (cabinet) or of the device; dimensions of the housing is 110 x 98 x 96 mm. The housing is made of shockproof, self-extinguishing material.

The product has four channels for temperature measurement, and four output load relays.

The temperature transducers (sensors) of the first three channels measure the temperature of each transformer winding; and the fourth one measures temperature of the transformer yoke.

In case of dangerous temperature rise of the transformer, the product first will enable alarm system and the cooling fans. If the temperature rise continues and the temperature exceeds the limit value, the product will perform emergency shutdown of the transformer.

In case of the temperature transducers fault, TR-100M enables the alarm of the transducer fault.

Product Details:

MCK 301-83 medium and deep refrigerating unit controller with automatic thawing is used to control freezer units, refrigerated counters, monoblocks and other commercial and industrial refrigerating devices.

The unit automatically maintains the freezer and evaporator temperatures as well as, depending on the mode of operation, either the second evaporator temperature or the temperature in the fan’s air flow.

If necessary, MCK-301-83 allows discovering and responding to the following emergencies:

• Short circuit or sensor breakout
• Leaving the unit door open for a longer time than allowed
• Unacceptable deviation in voltage parameters
• Sealing of starter output contacts
• Unacceptable over range of the compressor temperature
