Características principales
The transmitters intended for industrial applications detect the temperature with a Pt100 RTD temperature probe with 2-wire or 3-wire connection (Pt1000 linearization upon request). The output signal 4 to 20 mA is provided as temperature-linear. The continuous analog signal path allows for extremely quick output reaction times in the event of a temperature change (analog permanent measurement instead of digital sampling rate). This results in a low-noise and interference-resistant output signal. Maximum precision is ensured by range-specific amplification – even in small measuring ranges. The digital communication allows the transmitters to be adapted to the measuring task (measuring range, probe break, and fine adjustment). Two device versions are available to meet the requirements: Devices equipped with the basic type extension 880/990 (adjustable). The transmitters are adjusted to a fixed measuring range, but they can be adjusted to a different measuring range at any time via the PC setup program in conjunction with a sensor simulation. Devices equipped with the basic type extension 881/991 (configurable). The desired measuring range is configured with the PC setup program without sensor simulation or measurement.
