RKC Instrument
has announced the new AG500 microprocessor-based digital temperature indicator in a panel-saving 60 mm depth, 1/8 DIN case. ( Click here to hear additional comments from Leslie Whipple, RKC marketing manager .)

The company says it has worked to make the unit easy to read, using 21mm high LED numerals with luminance double that of conventional indicators for the five digit display.

Options available for the AG500 include universal input types, up to six programmable alarms, analog retransmission, digital input, 12 or 24 V dc sensor power supply, and RS-485 or Modbus-RTU communications. With digital communications, the indicator can be used in conjunction with a PC or PLC. With the analog retransmission output, it can be used with a chart recorder or data acquisition system.

In addition to the process high and low alarms, alarming standards of the AG500 include a latch function, an alarm timer delay, and hold action. The alarm status can be checked easily with alternate displays of process value and alarm number. The AG500 memorizes the maximum and minimum measured values. An optional contact input enables you to remotely reset the value.

Each unit carries a full three-year warranty. Typical applications include plastics and packaging machines, ovens, furnaces, kilns, textile dyeing, food baking, petrochemical, semiconductor, test stands, environmental chambers and other heated processes.
