285-6670 Pyrometer | |
The 285-6670 Pyrometer is an electronic scanner for exhaust temperatures. The scanner can monitor 24 points via standard type K thermocouples. An LCD displays the number of the channel and the temperature in °C or in °F. The scanner has two switches that can be wired to alarms or to relays. The scanner can provide readings, monitoring, and alarms for the temperatures of 20 cylinder exhaust ports and four turbocharger inlets and/or outlets.
The scanner has a microprocessor for processing the input signals. The microprocessor has non-volatile memory for storing programmable parameters and other data. The user interface is a keypad. The following functions are among the uses of the keypad:
- Change the display of the temperatures to °C or to °F.
- Select automatic display or manual display for the scan.
- Display a history of channels which have exceeded the setpoints.
- Change the filter for the display in order to stabilize the readings for a signal that is fluctuating.
- Program the temperature setpoints.
- Lock the keypad in order to help prevent changing of the non-volatile memory.
- Calibrate the scanner.
The scanner can monitor temperatures from 0 to 850 °C (32 to 1562 °F). Six temperature setpoints for the alarms can be programmed with the keypad. If an alarm occurs, the scanner has two output switches that can provide a signal to an indicator, to a switch, or to a relay.
