DA576 (Discontinued)
Precision Transmitter for Absolute and Differential Temperature Measurement
DA576 is designed for input signal from one or two Pt100 sensors in 4-wire connection and output in mA or V. Thanks to a unique design DA576 provides an outstanding accuracy of ±0.03 °C (±0.05 °F) in both absolute and differential temperature measurement.
DA576 can be calibrated for measurement spans down to 5 °C (9 °F), e.g. -2.5 to +2.5 °C. Each unit is delivered with a calibration certificate. The ideal transmitter for measurement of power/energy in hot water systems and efficiency in cooling systems.
- 1xPt100 (α=0.00385) input in 4-wire connection for absolute
temperature - 2xPt100 (α=0.00385) input in 4-wire connection for temperature
difference - Very small measuring spans for increased resolution
- Different output alternatives: 0-20 mA, 4-20 mA, 0-10 V
- True 4-wire sensor connection eliminates any influence of lead resistances
and imbalance - Plug-in terminals simplifies connection and disconnection
- DIN-rail mounting
- Each unit is delivered with a 4-point calibration protocol
