4-20 mA two-wire Dewpointtransmitter Model LDT Process Dewpointtransmitter The Model LDT is a „state of the art“ digital dewpoint transmitter. The unit is fully self contained in a stainless steel casing with weatherproof protection making it ideal for use in heavey industrial environments. The model LDT offers a 4-20 mA current loop and a HART interface output. 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.
