ZEVEX | LifeGuard Point Level Sensor
LifeGuard™ Point Level Sensor |
|
Proven and reliable liquid level monitoring technology in an all new package.
The new LifeGuard Point Level Sensor from ZEVEX successfully integrates proven and reliable technology in an extremely small and versatile package. The LifeGuard Point Level Sensor provides continuous liquid level monitoring and can be mounted using a disposable, self-adhering mounting piece or integrated into the customer’s product. ZEVEX’s patented design enhances ease of use by enabling the sensor to be acoustically coupled to the outside of a rigid vessel wall without the use of coupling gels.
The LifeGuard Point Level Sensor is designed for far wall sensing on reservoirs ranging from 0.3” to 5.0” or near wall sensing based on customer’s specific requirements. All LifeGuard electronics are integrated into the sensor housing, ready to interface with the user’s system. ZEVEX engineers can tailor our sensors to work with your specific reservoir.
