New controllers for radar transmitters
By Gerald Ondrey |
The new Sitrans LT500 level, flow and pump controllers (photo) are suitable for radar and ultrasonic transmitters or any other two-wire 4–20-mA devices. From basic level control to complex pumping routines, these instruments deliver the accuracy and reliability demanded by a variety of applications. Complete with up to two measuring points, six control or alarm relays, two discrete inputs, three analog outputs and communications options, Sitrans LT500 is an attractive option for controller applications. Users can easily retrofit older equipment with Sitrans LT500, as improved system control delivers savings directly to a company’s bottom line. By scheduling pumps before high-demand periods begin, users can avoid peak energy hours and the increased prices that accompany them. — Siemens AG, Munich, Germany
