Senix ultrasonic level sensor

Description

The Senix ToughSonic TSPC ultrasonic level sensor can be used to measure water

level in tanks, channels and dams. The level measurement can then be used as a

trigger to send alerts or automate pumping equipment.

Electrical connection

• The Senix TSPC 485 versions are standard Modbus RS485 serial

communications devices

• Connection to the C3 is made via the 2 m 4-way cable, this can be

extended if desired using appropriate cable jointing methods

Installation notes

• The 30S1 is supplied via Observant with a stainless steel bracket that

allows screw mounting to horizontal surfaces, otherwise the sensor can

be mounted directly through a hole sized for an M30 thread (Two M30 nuts

are supplied)

• The body of the 21S is un-threaded and requires mounting via u-bolts or

similar

• The body of the sensor must be shielded from direct sunlight. The internal

temperature compensation of the measurement is only effective if the

sensor and ambient temperatures match
