- Measuring of the pressure-differences of gases
- 8 measurement ranges between 0-5000 Pa
- Medium temperature: up to 60 °C
- 4-20 mA two-wire transmitter
- Intrinsically safe
- IP 65 protection
The DT7001 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 DT7001 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 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.
|The connection terminals of the supply voltages are isolated from each other, the isolation is in compliance with the standard EN 61010-1, taking into consideration the following:|
