New products arrive from AutomationDirect
US-based industrial control business AutomationDirect has added the Flowline EchoTouch, EchoSpan, and EchoSwitch lines of ultrasonic liquid level sensors and transmitters, as well as the PodView digital level indicator to its product offerings.
Constructed with PVDF transducers and NEMA 4X polycarbonate enclosures, these sensors replace float, conductance and pressure sensors that fail due to contact with dirty, sticky and scaling media in small, medium and large capacity tanks. Ideal for chemical, water and wastewater applications, these general purpose sensors are available with single and multi-function capabilities including continuous level measurement, switching and control.
The Echotouch LU20 liquid level transmitter features continuous level detection up to 18ft, adjustable dead band and range filters eliminate false echo returns.
The EchoSpan LU series ultrasonic liquid level transmitters provide continuous level measurement up to 32.8ft with a 4-20 mA signal output.
The EchoSwitch LU series ultrasonic liquid level sensors provide continuous level measurement up to 26.2ft and three programmable relays provide level switch or level control functions and a 4-20 mA output. Relays can be configured on a single setpoint or latched on two setpoints for automatic fill or empty in simplex, duplex, triplex level control modes with selectable time delay and fail-safe logic.
