EchoSwitch II, Second Generation Non-Contact Level Switch and Controller
Unique Features
- Simple digital push button configuration, no more target calibration.
- Pump simplex, duplex and triplex option.
- Integrated timer for pump/valve delay and pump alternation.
- Available in a 7.5m (24.6') or 2.5m (8.2') maximum range.
- 10 cm (4") miniature dead band optimizes the filling capacity of sumps or vessels.
Description
The general purpose ultrasonic switch and controller provides non-contact level detection up to 24.6' (7.5 m) with 3 SPDT 60 VA 1A relays. EchoSwitch II features digital push button configuration, eliminating target calibration. Each relay can be configured on a single set point to control pumps, valves or alarms. In addition, all 3 relays can be simplexed, duplexed or triplexed. EchoSwitch II now features an integrated timer with pump/valve delay and timed pump alternation. The switch is well suited for a broad range of corrosive, waste and slurry type media. EchoSwitch II is broadly selected for atmospheric day tanks, pump lift stations and waste sump applications.
