K-13 0.3 to 7.6 m (1 to 25') Range Exclusive VSS Sensor Sense™ with 34 NPT Mounting Programmable Zero and Span Through BCD Switches Direct Replacement of Capacitance System CSA Approval— Intrinsically Safe and Explosion Proof Rating with 316SS Sensor, PTFE, Sensors STD Near Zone Varies from 152.4 to 305 mm (6 to 12") The LVU1500-LP Series Two-Wire (“Four-Wire” for four wire unit), non-contact continuous level transmitter, is easy to program, can be used in hazardous locations, and offers unique stainless steel and 34 NPT sensors. It is a great choice for sanitary, hazardous, dirty, corrosive or high purity processes. The 4 to 20 mA output is compatible with all control systems and updates quickly making the LVU1500 Series the right choice for fast filling processes. The LVU1500 Series is plug-andplay. Digital signal processing, and automatic temperature compensation eliminates all adjustment except zero and span. Zero and span calibration is set directly in inches using digital switches and requires no power. The rugged epoxy coated aluminum enclosure survives where plastic enclosures fail. Operation The sensor is mounted on the top of the tank. The electronics generate an electronic signal that is converted by the sensor to ultrasonic pulses that are transmitted through air space. At the liquid/air interface, the pulses are reflected back to the sensor. These echoes are received by the microprocessor in the electronics, which samples the echoes and calculates the level in the tank. A continous output of 4 to 20 mA (isolated) adjustable in increments of 1"/0.1" over entire span is provided to satisfy a number of applications. Programming is done through a pair of BCD switches.
