Specification
UNB 400 ( Basic )
For standard temperature control applications with insensitive load, the Basic class is recommended. An electronic PID controller with an integrated self-diagnosis system ensures reliable and exact temperature control.
* Temperature range: 30 ° C ( at least 5° C or 10° C above ambient) to 220 ° C
* Temperature variation ( time) : < ± 0.5 ° C at 150 ° C
* Double overtemperature protection: If the electronic heating control should fail, heating is switched off at a fixed level of 10 ° C above the setpoint. In addition a mechanical temperature limiter, TB, switches off heating permanently if the maximum permitted oven temperature is exceeded by approx. 10 ° C.
* A high-quality platinum temperature sensor Pt100 ( DIN class A) in a 4-wire circuit ( for stable long-term transmission of measurement signals)
* Programmable digital timer ( 1 min. to 99 hrs 59 min.)
* Manually adjustable air flap for fresh air intake
* Visual alarm if temperature is exceeded
* Function signals for stand-by, operating mode, heating and overtemperature
