AirWire® LoRa
As of 2025, Senix's LoRa spread-spectrum wireless technology has been discontinued.
This includes the entire AirWire family, including level transmitters, receiver-gateways, and associated accessories.
As a replacement, Senix suggests BinCloud® bulk inventory software—as well as its six tailored software "Views"—for remote monitoring of ToughSonic® distance and level measurements.
For assistance with existing AirWire systems, please contact Senix.
ULTRA-S
For direct physical replacements of the ULTRA-S system, Senix recommends the ToughSonic® 14 or 30 ultrasonic sensors.
This provides the user with the latest ToughSonic sensor features, plus SensorView™ software.
Current ToughSonic models include all electrical interfaces that were implemented with the ULTRA-S, except for internal AC power, as all replacements are DC-powered.
ULTRA-U & ULTRA-U-SS
Senix customers using the obsolete ULTRA-U or ULTRA-U-SS ultrasonic sensors can opt for a new ToughSonic®-100 (general purpose) sensor of their choice, depending on measurement range and mounting requirements.

ULTRA-30-VA
ULTRA-30-VA sensors can be replaced by the ToughSonic® 14.
This sensor is a bit smaller than the discontinued product, has identical 30mm threads, a greater range, is more rugged, and provides more features.
ULTRA-100
Senix does not currently have a direct replacement for the ULTRA-100 single relay proximity switch.
