Pressure Sensor

Low Differential Pressure Sensor

The EE610 is dedicated for the highly accurate measurement of low differential pressure in applications like clean rooms, hospitals, laboratories, isolation chambers or in the pharmaceutical industry. It is suitable for air as well as all nonflammable and non-aggressive gases.

Measurement Performance
The EE610 offers ±0.5 Pa accuracy over the entire measurement range. For the versions with analogue outputs, the measuring ranges ±25 / ±50 / ±100 Pa and 0…100 Pa (±0.1 / ±0.2 / ±0.4 and 0…0.4 inch WC) are selectable with DIP switches. The piezoresistive, no flow-through pressure sensing element stands for outstanding long-term stability.

Analogue and Digital Outputs
The measured data is available on the analogue voltage and current output or on the RS485 interface with Modbus RTU or BACnet MS/TP protocol. Functional and Robust The IP65 / NEMA 4X enclosure minimizes installation costs. External mounting holes allow installation with closed cover, the electronics are thus protected against construction site damage and pollution.

Configurable and Adjustable
The setup can be easily performed with DIP switches on the electronics board (EE610 with analogue output) or with an optional adapter and the free PCS10 Product Configuration Software. The setup includes measuring range, output signal, response time, displayed units and backlight. The auto-zero interval and the measuring range can also be set with the PCS10. A zero point and span adjustment can be easily performed with push buttons on the electronics board. 

single- or two-sided diaphragm seal is a pressure transmitter for differential pressure, level, density and interface measurement. It can be used in pressurised pipes, tanks and closed vessels. Its wide selection of inline or membrane diaphragm seals makes it particularly suitable for extremely aggressive and corrosive media, abrasive and highly viscous liquids or for hygienic applications. For applications with sudden pressure and temperature changes (up to +400°C / +842°F) or vibration, the pressure transmitter can be combined with one or two capillary diaphragm seals. The differential pressure device comes with a wide range of process connections. It has approvals for use in hazardous areas and comes with various digital communication options.

Differential pressure transmitter with integrated absolute pressure measurement. It is the ideal choice for general flow, level and differential pressure applications. The DP transmitter is currently the most compact pressure transmitter in the market – worldwide. This makes it particularly suitable for space-saving installation in applications with limited space, e.g. in mechanical and technical plant engineering.
