Analog Output

The LDT-transmitter supplys a linear 4-20 mA current over the full measurement range.

 

Nano – Pore Sensor

The LDT-Transmitter uses a high capacitiy nano-pore sensor with a very fast response time and high stability.

 

Digitaler Signalausgang

The device utilizes a simple digital protocol driven on an HART interface. The command structure (protocol) allows the user, via software, to obtain the dewpoint, temperature and perform diagnostics.
Various ranges are available covering an overall range from –110°C to +20°C dewpoint.
The Model LDT-transmitter derives its power from 5V – 28 VDC non-isolated power source.
