Description
HD 788TR1, HD 786TR1, HD 988TR1 and HD 988TR2 are 4-20 mA transmitters with a microprocessor, configurable for Pt100 Platinum temperature sensors.
They convert the temperature variations found with any standard Pt100 sensor
( 100© at 0° C) into a linear current signal with two leads in the field 4÷ 20 mA.
Linearisation with a digital technique allows excellent precision and stability to be
obtained. The 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 transmitters are also protected against inversions of polarity. The HD 788TR1 is specifically designed for installing in type DIN B connecting heads, while the HD 988TR1 and HD 988TR2 are suitable for fitting in containers with a 35 mm DIN bar connection. As well as the 4÷ 20 mA output, the
HD 988TR2 has a convenient 31D2 digit display ( height 10 mm) which allows the display of the measured temperature. Suitable for fitting on the wall.
