Transceivers are equally good at both transmitting and receiving an ultrasonic signal. Typically wide beam is good for robotic collision control, security applications and level monitoring of solid objects; while narrow beam is better for liquid level monitoring and surface or profile imaging. High frequencies are good for detail and low frequencies are good for range.

Wide Beam Ultrasonic Sensors useful for ranges from 0.1m to 50m

40Khz sensors using straight forward signal conditioning techniques can be applied for ranges from 0.2m to about 20m. Using signal processing techniques this range can be expanded to 40m and beyond.

25Khz sensors using straight forward signal conditioning techniques can be applied for ranges from 0.3m to about 30m. Using signal processing techniques this range can be expanded to 60m and beyond.

Ultrasonic Signal Conditioners and Converters (Size 50 x 50 x 15 mm)

Signal conditioners help bridge the gab between the monitoring device and the sensor. These are composed of a driver and an amplifier. The driver is normally controlled by the device using the sensor to gather information, and it possesses sufficient power to fully excite the sensor. The amplifier boosts the amplitude of the returning or received signal, so that it can be monitored using an ordinary analog to digital converter or a comparator. The converters contain an additional processing unit to simplify operations.

Ultrasonic Proximity Switches (Details)

• Low Power Consumption

•  Size (50 x 50 x 23 mm)

HXS series is a low cost switch USD 42 in hundreds. It uses a wide beam transceiver, and is therefore less sensitive to the orientation of the object tripping the switch. When the object comes within a given distance (see table below) from the device the brown wire goes from off state 0V to an on state (Vsupply). This device is capable of sourcing 100mA to a voltage level of 0.8*Vsupply. The table below is a general selection guide, if you don't find a device that suits your application, let us know we can change the parameters.

* Power consumption is measured with the brown wire open (not connected)

Short Range Ultrasonic Distance / Proximity to Voltage Converters 

• Low Power Consumption

• Size (50 x 50 x 23 mm)

HXC series is a low cost distance monitor USD 59 in hundreds. It uses a wide beam transceiver, and is therefore less sensitive to the orientation of the object. It is useful for position or level measurements in cases where the objects are not necessarily flat and orderly. And it may also be useful for liquid level measurement. The table below is a general selection guide, if you don't find a device that suits your application, let us know we can change the parameters. More information.

Medium Range Ultrasonic Distance / Proximity to Voltage Converters 

• Size (50 x 50 x 23 mm)

HXC series is a distance monitor priced at around USD 98 in hundreds. It uses a broad beam transceiver, and is therefore less sensitive to the orientation of the object. It is useful for position or level measurements in cases where the objects are not necessarily flat and orderly. And it may also be useful for liquid level measurement. The table below is a general selection guide, if you don't find a device that suits your application, let us know we can change the parameters. More information.
