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.

Pro-Stik II - Intrinsically Safe Programmable Linear Position Sensor
The Series 7330 Pro-Stik II supersedes the 7220 and 7300. This product combines the reliability and resolution of magnetostrictive continuous absolute positioning sensing with the Stik package to create a unique level measuring instrument.
The magnetostrictive technology is the same as used in Gemco LDT sensors. Ametek liquid level sensors, have been proven in demanding applications such as underground leak detection and inventory management. The 7330 is available with a rigid 316 stainless steel or flexible PVDF materials.

The 7330 also is available in an explosion/flame proof design. The 7330 EX/ED Series Pro-Stik II takes field proven magnetostrictive sensing technology and incorporates features such as explosion/flame proof design and field programmable span. This is packaged in our patented Stik design, making the Pro-Stik II ideal for level monitoring in a variety of liquids and tanks.

Electrode Holders Series 6012

B/W Controls offers a variety of electrode holders to meet mounting, pressure, and temperature requirements. Most holders have watertight protection for conduit or cable entrance.  Ametek offers holders and electrodes in many different materials for the most corrosive or high temperature applications.

Electrodes and holders should be selected according to the specific characteristics of the liquid involved, the lengths required to obtain the desired control of levels, and the physical nature of the container. Because of these factors, the B/W line of electrodes and holders presented in this section has been developed to provide a practical, economical solution to almost every conceivable application and installation problem. When necessary, special equipment can also be supplied to meet specific needs.

The B/W electrode sensors are available in several varieties: solid rod (rigid), wire suspension, and standard gland plugs for high vibration applications.  In addition, we offer custom options made per customer’s requirements.  Electrodes made from 316SS, Brass, Monel, Nickel, Carpenter 20, Hastelloy B, Hastelloy C, and Titanium provide compatibility for almost all applications and environments.  We cover the sewage pumping stations, elevated tanks, shallow and deep wells, hydropneumatic tank, storm drain type, cooling towers and many more applications.

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.

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.

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 locations.

Digital Stik - The 7250 Digital Stiks take field proven magnetostrictive sensing technology and packages it for greater reliability and easier installation. It is ideal for liquid level monitoring, interface level and leak detection in a variety of liquid media in above ground and underground storage tanks. This series has an inherently lower cost design which results in savings. It provides the same performance and reliability as sensors that consume more power.

The 7250X Digital Stik is constructed of 316 Stainless Steel and comes with a variety of connectors, including a mini connector for quick connect applications, a single 3/4” NPT that can be used with a compression fitting, a double 3/4” NPT for mounting with a flange or bushing, and a 1/2” right angle for use in low overhead applications.
