New to Range, the DS1500 with RS485 and MODBUS (RTU) is a digital dewpoint hygrometer and fully compatible with the Alpha Moisture Systems’ AMT, PDT and AMT-Ex Dewpoint Transmitters for continuous trace moisture measurement in most gases and dry compressed air.
The DS1500 system is factory configured to user specification to read in either °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ or lbs/MMSCF. The measured value is displayed on a large six-digit red LED display.
DS1500 offers a selectable 0-20 mA or 4-20 mA isolated retransmission signal and four programmable alarm relays.
A digital communication channel is provided via a RS485 (MODBUS RTU Communication Protocol) serial connection for remote interrogation of measured values and status of alarms and instrument.
Instrument configuration is achieved from the front keypad, without any hardware change. The selection of input type and alarm modes and other special functions, are also accessed and defined from the front keypad.
