ETTN-YTTN Serisi Dijital Sıcaklık Anahtarı
ETTN range digital temperature switches are intended for temperature control for industrial process management.
Based on microprocessor technology, the temperature switches can be
programmed completely on site using code protected keys.
The output signal (4…20 mA or 0…10 V) is adjustable between
-200°C and 400°C.
It is possible to reduce the errors due to thermal resistance of the
pipe or thermowell by manually entering the process fluid temperature
into the ETTN.
The ETTN range comprises three models: with the temperature
measurement by a submerged probe, deported probe or by surface
