Wavetronics develops and providesmanufactures and offers microcontroller-based cold room digital temperature controllers. These digital temperature controller finds its applications in to meet any custom-built application like in laboratory or pharmaceutical or food processing industries. Some of the technical features of these controllers include: delay time 0 to 200 second adjustable, defrost on time 0 to 720 minute adjustable, defrost off time 1 to 720 minute adjustable, defrost timer on/off cycle start below -1.0c and reset above -1.0c open display if rtd [sensor] break, etc. All relays trip and give alarm if rtd break or open. Defrost on/off can be done manually with increment key. Heater on/off can be done manually with heater key. Heaters off after 10 minutes automatically. Size available is 192 mm x 96 mm.Following are some hardware features of these controllers:these digital temperature controllers are available in single 4-digit display for process value indication, with inut signal rtd pt-100, and outputs like relay contact for motor, relay contact for fan, relay contact for heater, buzzer output cooling control, etc. Other features includes temperature ranges from -50.0 to 50.0 adjustable in set mode, . Aalarm setting range is from 0 to +10.0 or -10.0c with respect to set temperature. Alarm with mute facility is by decrement key,. Hysteresis [difference] is 0.1 to 20.0c adjustable. Password facility for configuration mode is to avoid unauthentic entry. Features include: delay time 0 to 200 second adjustable, defrost on time 0 to 720 minute adjustable, defrost off time 1 to 720 minute adjustable, defrost timer on/off cycle start below -1.0c and reset above -1.0c open display if rtd [sensor] break, etc. All relays trip and give alarm if rtd break or open. Defrost on/off can be done manually with increment key. Heater on/off can be done manually with heater key. Heaters off after 10 minutes automatically. Size available is 192 mm x 96 mm.
