Temperature Transmitter DR 49
Temperature Measuring with Pt1000-Sensors
The Temperature Transmitters DR 49 converts the sensor signal on input to temperature linear standard signal and makes it galvanic isolated available on output.
- Cost optimized design
Economical temperature measuring for standard applications with Pt1000 sensor with 2-wire or 3-wire connection - Only 60 mm installation depth, 11.2 mm wide
Can be installed in economical standard terminal boxes - Fixed ranges, easy to use
Ready to use without any settings or adjustments - Zero/Span compensation on front panel
for readjustment of sensor signal or measuring equipment - True 3-port separation
Protection against erroneous measurements due to parasitic voltages or ground loops - Protective Separation acc. to EN 61140
Protects service personnel and downstream devices against impermissibly high voltage - Unlimited use with 24 V AC/DC power supply
Universally applicable for all measurement and industrial applications - 5 Years Warranty
Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)
For applications where one measuring range only is used, the Temperature Transmitters DR 49 offers a cost-effective alternative.
A cross-connector for the auxiliary power supply ensures fast and easy installation. The slim housing with 11.2 mm width saves significant space on the DIN-rail. If required a measuring range compensation can be performed at the Zero/Scan potentiometers behind the front cover.
Analog signal processing guarantees precise measured values with short response times and outstanding signal reproduction at the output.
Protective Separation and the 24 V AC/DC power supply make the Temperature Transmitter DR 49 universally applicable for all measurement and industrial applications, as well as for building automation.
