3 - I N -1 o r 4 - I N -1 M O N I TO R I N GThe OleumTech® LL3 Resistive Liquid Level Transmitter is

capable of monitoring product, interface, and temperature,

making it ideal for industrial tank level applications. The level

output in inches or cm. Additional data such as volume and

tank full % can be reported as well based on user preference.

The LL3-D offers 1x discrete input, providing 4-in-1 capability.

S E N S O R O P T I O N SThe Resistive Transmitter mates to either OleumTech Flex or

Rigid Resistive Sensor that is sold separately. The flex sensor is

available in 8 to 38 ft (2.4 to 11.6 m) lengths while the rigid

sensor is offered in 2 to 17 ft (0.6 to 5.2 m) lengths. Both

versions are available in 1 ft (0.3 m) increments and can be

ordered with a single or dual-float configuration option.

LO C A L D I S P L AYThe device features a 32-character local LCD display for

instantly reading process data, battery voltage, and RF strength

(RSSI). When the display is set to configuration mode, users

can set all of its parameters, perform calibration, and connect to

a network just using the push button interface without the need

of any configuration cables.

B AT T E RY- P OW E R E DThe LL3 and LL3-D Transmitters rely on power from a replace-

able battery. The system is engineered to achieve maximum

battery life, providing +7 years of life from a single battery1.

I N T R I N S I C A L LY SA F EDesigned for use in Class I, Division 1 (Zone 0) hazardous

locations. These Transmitters are intrinsically safe, meaning

they cannot a cause a spark and can be serviced without being

removed from a process.

B re e Z ® S O F T WA R EThe OTC Sensor Network is managed using the BreeZ Software

by OleumTech, provided free of charge. The Resistive

Transmitters can be configured using the push button interface

or BreeZ Software.

CO M MU N I C AT E S W I T H W I R E L E S S G AT E WAYThe Resistive Transmitter is one of many Wireless Transmitters

that communicates with an OleumTech Wireless Gateway within

its network, creating a highly scalable network, accommodating

virtually any level or I/O requirement.
