4 to 20 mA Transmitter Boards for

Alphasense "B" Type Toxic & O2-A2 Oxygen Sensors

PATENTED

Figure 1 Toxic and Oxygen Sensor Transmitter Boards

Alphasense 4-20 mA transmitter boards provide a cost effective way for Original Equipment Manufacturers to engineer transmitter heads for fixed installation systems. The range of sensors are shown in Table 1. The boards supplied with sensors are pre-calibrated.

The 4-20 mA output signal provides an equivalent performance to that shown in individual sensor data sheets provided for each of the Alphasense "B" Series Toxic and "A" series two year oxygen sensors.

Each board is provided with set of mounting pillars for location of the board onto an enclosure. To allow OEM's to distinguish their product from other offerings, the sensor to gas aperture design is left to the OEM to execute.

Alphasense transmitter boards offer © exceptional stability. © minimal settling time when put on load. © wide operating voltage range and © low RFI susceptibility through the use of an unbroken ground plane.
