DT700 DP / DT701 DP Differential Pressure Meter / Transmitter
Product description
The DT700 DP / DT701 DP Differential Pressure Transmitters are suitable for measurement differential pressure of dry non corrosive gases.
The instruments provide 4-20 mA current signal, proportional to the pressure difference connected to their pressure ports.
The DT700 DP presents the measured pressure value on an LCD display too, while the instrument DT701 DP is a version without display.
Eight different measurement ranges are available from 0-50 Pa up to 0-5000 Pa, but user defined measuring ranges are also available. The temperature of the measured medium may vary between -20°C and +60°C.
The signal to be measured can be connected to the transmitter via pneumatic tubes have 2 × Ø 4 mm inner diameter.
The die-cast aluminium housing has IP 65 protection.
