AUTO TUNE PID TEMPERATURE CONTROLLER CUM LOGGER
Version : PID-1P

   
  Introduction
 

This controller is a PID temperature controller with auto tuning facility for controlling temperature in BATHS / MUFFLE FURNACES / OVENS / VACUUM OVENS etc. The instrument accepts RTD sensor (1 no). The indicating accuracy is ± 0.1° C throughout the operating range (0 – 270.0 ° C). The control accuracy is ± 0.5° C. Sensor break indication is provided and is displayed as “OPEN”. It is a PID on-off type of control with a SSR(solid state relay) drive output. The heater status is shown on the LED marked ‘HEAT’. High & Lo Alarms are provided, in case the temperature goes above or below these values.

Real time recording is provided with up to 6000 readings storage capacity. The real time clock & calendar chip keeps time. It is battery backed with an auto re-chargeable Ni-Cd battery. The logging interval is user selectable (1 – 99 minutes). For example, if logging interval is set to 1 minute, 100 hours of data can be stored; whereas, if logging interval is set to 45 minutes, approximately 6 month of data can be stored.

WARNING :- After 6000 memory locations have been logged, the new data is over written on memory location 1 onwards. The printing is not on-line, but only on request. The printer should be attached to the unit only when a hard copy is needed. This implies that only one printer is needed for many incubators.
The print interface is a serial interface type : RS 232 C with selectable baud, 1 start bit, 8 data bits and no parity bit. As such, it is directly compatible with any dot matrix printer with RS 232 C port e.g. LX-300, LX-300+ (EPSON).
