Description
Temperature Measuring Transducer MU125M with Universal Input
The measuring transducer MU125M converts a temperature measuring value or a resistance measurement value from various sensors to a current signal of 4..20mA. The universal configurability of the measuring inputs reduces the stock requirement for various applications. The housing width of only 12.5 mm enables space-saving installation in the switch cabinet.
Technical data:
Wide-range power supply:
Supply voltage: 20-125VDC and 20-250VAC (47-63Hz), max.1.5W
Common data:
Rated voltage: 253V AC
Test voltage: 3kV AC between supply // input = output
Working temperature: -10 to +60°C
Storage temperature: -20 to +80°C
Humidity: 10-90% (non-condensing)
Measurement inputs:
Pt100: linearised, measuring current ca.1.6mA
Pt1000: linearised, measuring current ca. 130µA
In the event of a sensor break or short circuit, the analog output drops to 0mA. The operation LED blinks red.
NTC: linearised for B25/85=3977K or 3528K. Max load 200µW (averaged)
Linear resistance: Mb. 0-2kOhm: ca. 1,4mA
Mbs. 0-5kOhm, 0-10kOhm: ca. 300µA
Zero point setting: ±40% of the factory measuring range (= end value - start value) via 12-turn trim potentiometer
End value reduction: -50% based on the factory end value via 12-turn trim potentiometer.
Note: Themeasuring accuracy drops proportionally with the narrowing of the measuring range.
Potentiometer setting limits: Limitation of the aforementioned adjustment ranges
