Continuous Level Measurement - 7230 HT Digital Probe
|
DESCRIPTION
Measure Condensate, Oil and Water, and other Mixed-Liquid Tanks. No Calibration Required. Provides Total Level,
Interface Level and up to 5 Temperatures. Independent of Changes in Process Material's Electrical Characteristics and Densities. Modbus RTU,
and Proprietary ASCII Digital Protocols Available. High Temperature Applications. Temperature Range to 257oF. High Accuracy of 0.01%
The 7230 Series HT Digital Probe is a magnetostrictive probe for high temperature applications in the oil and gas industry including pipeline
tanks and oil and water separators. The level sensor provides a multi-variable output that includes level, interface and temperature data that
only requires one process connection.
There are two communication protocols available. The 7231 with Modbus RTU is the standard protocol. The 7235 comes with a proprietary, ASCII
protocol and is recommended for OEM applications. An optional Analog interface is also available.
What is impressive about this instrument is that the measurements are completely independent of changes in the process material's electrical
characteristics and densities. Hydrocarbon based condensates have a predictable range of specific gravity that are well within the range of the
standard floats, which means that variations in hydrocarbon make up will not cause level measurement errors. In addition, the measurements are
not affected by vapors, stratification, or temperature changes. This makes the 7230 Series probe ideal for applications where liquids with
different physical characteristics are mixed in one tank such as condensate and separator tanks.

Point Level Floats - 7010 Tilt Switch Float Assemblies
 |
DESCRIPTION
7010 Tilt Switch Float Assemblies - The B/W Controls Float Switches are tilt actuated liquid level controls, designed to operate pumps, valves,
multiple alternators, relays, contactors, alarms and similar equipment for industrial and commercial use. The wide angle, tilt-option uses a
mechanical switch inside the float, while a hermetically sealed, axially nonposition-sensitive mercury switch is the narrow angle option. These
floats provide a reliable, long-lasting level control suitable for most liquid environments up to 160 F. The B/W Tilt Float Switch provides an
ideal pilot device for the control of all B/W relays and controls panels. The polypropylene float, PVC cable, and hermetically sealed mercury
switch provide an economical liquid level solution for controlling sewage, effluent, many chemical solutions, as well as liquids in other
hostile environments containing oil, grease or other similar industrial and municipal wastes where dependable liquid control is essential.

7014 Unifloat
 |
DESCRIPTION
The B/W Unifloat level sensing system was developed especially to permit simple, low-cost installation and ease of adjustment in service for a
broad range of applications requiring accurate multiple function/multiple level control of any type of liquid. The unique design of the patented
Unifloat features a Latching Reed Switch that eliminates the need for multiple floats to indicate various switch points. The B/W Unifloat
Assembly is available in two styles: one lead with grounded contact or two leads with isolated contact. Both offer a latching reed switch for
greater flexibility and can be used with all the B/W control relays and control panels. The isolated contact design can directly interface to
programmable controllers.

OEM Product Continuous Level Measurement - 7100 Leak Detect Stik
 |
DESCRIPTION
Leak Detect Stik - The 7100 Stik Liquid Level Sensor takes field proven magnetostrictive sensing technology and packages it in a revolutionary
new way for greater reliability and for easy installation and mounting. All sensor electronics are SMT components integrated into the 5/8"
diameter sensing tube. This breakthrough in package design eliminates the bulky electronics enclosure at the top of the sensor and offers you
greater options for insertion. The 7100 Stik has PPM (Pulse Position Modulated) outputs for product and interface level and for temperature
measurement, which are all superimposed on the two wire power line. All units are Intrinsically Safe and approved for use in hazardous
