HDXXX Temperature Transmitter
Brand: Delta OHM S.R.L.These are 4÷20 mA configurable transmitters with microprocessor for Pt100 Platinum temperature sensor.
They convert the temperature variations found with any standard Pt100 sensor (100Ω at 0°C) into a linear current signal with two leads in the field 4÷20 mA.
Linearization with a digital technique allows excellent precision and stability to be obtained.
User can set the 4÷20 mA output (or 20÷4 mA) in any temperature range within the field -200...+650°C, with a minimum amplitude of 25°C; it may be simply reprogrammed by pressing a key, without any need to regulate jumpers, potentiometers, software, etc.
A led indicates any alarm situations (temperature outside the set range, broken or short-circuiting sensor) and assists the user in the programming phase.
The 4÷20mA output of models HD788TR1-I and HD988TR1-I is galvanically isolated from the Pt100 input.
The transmitters are also protected against inversions of polarity.
