Dual Timer Capacitance Probes
These dual timer capacitance probes feature a flexible time delay for covered and uncovered conditions. This feature allows the user to set a probe to react either immediately or with up to a 30-second delay when it detects a covered or uncovered state. For example, the capacitance probe can be set to send an immediate alert when it reaches a covered state, but can be set to alert with a 15-second delay when it detects an uncovered state. The dual timer capacitance probe is ideal for applications when it is essential for the probe to alert immediately to a covered state when used for high-level detection, as in situations when the probe is used to shut off a filling process. When the probe reaches an uncovered state, that same probe can be set to alert with a selectable one- to 30-second delay. BinMaster, Lincoln, NE 800-278-4241 www.binmaster.com

Flow Meter
The MaxxFlow is designed to measure medium to high flow rates (10–600 tn/hr) of powders, pellets, and granules. In the past, only complex mechanical systems like impact flow meters and weigh feeders were possible. Advanced technology in electromagnetic velocity measurement and microwave concentration has produced an open cross-sectional spool piece less than 16 in. long. This meter can fit anywhere in your process under free-fall or sliding conditions with no straight run requirements. The system is ideal for truck and railcar load outs or process measurements after rotary valves, screw feeders, bucket elevators, air chutes, etc. The accuracy is +/- 1-3% with repeatability to .2%.

Automated Synthesizer
Zinsser-Analytic and Thales Nano have teamed up to develop a highly flexible automated synthesizer that combines many functions on one platform. Sophas Hy utilizes the functionality of Zinssers proven Sophas Synthesizer, such as heating, cooling, and mixing, in line with the continuous flow chemistry reactor H-Cube by Thales Nano, allowing the full automation of sample preparation, batch and flow chemistry. Several optional tools can be included on a modular basis to meet the needs and demands of the work flows required, such as powder handling, weighing, microwave-assisted synthesis, sonication, and pH-measurement and titration.

Bin Level Indicator
The Model RH rotary paddle bin level indicator incorporates local high-intensity indication as a standard feature. The Model RH combines bright LEDs for local indication of Normal and Alarm status with four shaft bearings for smooth operation and long life, a DPDT relay output that is fail-safe on power failure - a standard offering that replaces other brands using existing paddles and accessories - an automatic motor shut-off to extend motor life, and a 90-day golden parachute return policy along with an industry standard two-year warranty. The Model RH is offered for ordinary electrical locations certified to meet CSA/UL 61010 standards and the Model RHX is for hazardous areas (certification pending).

Control Systems & Batching Automation
These control systems include integrating personal computers, programmable logic controllers, and equipment for weighing, batching, and process control systems. Using Windows-based hand prompt batching controls, the systems provide accurate minor ingredient weighing. An operator interface panel is used in conjunction with a scale to sequence operator through pre-programmed formula, one ingredient at a time. Customized controls are designed around the application requirements, bin volumes, feed type, size, and scale capacity. The batching controls provide formulation storage and inventory of raw materials and finished batches along with real-time batching status, weighments, batching status, and “material in suspension” correction.
