Air Velocity Sensor

The Series 641RM Air Velocity Transmitter with Remote Probe features the same highly accurate heated mass flow sensor as the Series 641, with a remote probe construction. The units 6´ cable which connects the sensing probe with the electronic enclosure allows the enclosure to be mounted where it can be more easily accessed.

NIST CALIBRATION available in Product Configurator.

The EE660 air velocity sensor operates on the hot film anemometer principle and is optimised for precise measurement of very low air velocity in laminar flow monitoring and clean room applications.EE660 employs E+E air flow sensors manufactured in thin film technology, which stands for excellent accuracy and long-term stability down to 0.15 m/s (30 ft/min). The device is available with current and voltage output or with RS485 interface an Modbus RTU or BACnet MS/TP interface. EE660 is user configurable and adjustable with jumpers on the electronics board or with the EE-PCS Product Configuration Software.

  • Monitoring of laminar air flow cabinets

    Laminar flow cabinets are used as local clean rooms for the production, assembly and testing of sophisticated products with high quality standards. The directed, turbulence-free air flow reduces the suspension of existing particles and removes them with the downwardly directed air flow

The Series AVU Air Velocity Transmitter is ideal for a wide range of HVAC measurement and control applications, particularly in complete building control and energy management systems. The Series AVU Transmitter operates by measuring the heat loss from one of the two sensing elements in the air stream, then calculating the air velocity. Units are virtually immune to drift due to the design of the sensing element, which makes the transmitter accurate over the whole air velocity range.

PRODUCT APPLICATIONS

• Supply and exhaust fan tracking
• Clean room systems
• Air pollution studies and manufacturing
• Zone control in HVAC systems
