DT7000 Intrinsically Safe Differential Pressure Meter / Transmitter
Product description
The DT7000 Intrinsically Safe Differential Pressure Transmitters are suitable for measurement differential pressure of dry non corrosive gases in even the most hazardous plant areas (zone 1, zone 2).
The instruments provide a 4-20 mA current signal, proportional to the pressure connected to their pressure ports.
The DT7000 presents the measured pressure values on an LCD display too.
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 pressure to be measured can be connected to the transmitter via pneumatic tube 2 × Ø4 mm inner diameter.
The die-cast Aluminium housing has IP 65 protection.
