"It isn't rocket science."

It shouldn't be at any rate. Sensor figures what is suppsed to happen, and then machine reacts, right? But what sensor?

-Laser
Great for determining pit and tank fill levels, particularly when you have changing needs with changing seasons and conditions. Easy and precise, with quick response time, ideal for setting desired fill/drain levels.

-Level Transducer

Ideal for water/wastewater applications with variable levels; rugged and not bothered by caustic or dirty material. Quick and precise response; not bothered by agitation or foam.

-Float Switch

Cost effective and simple, perfect for applications where a simple full or empty indication is all that is needed to initiate action. Easy maintenance, and available in both dirty and clean varieties.

Safety sensors

-Proximity switch

safety in its simplest, set to react when the sensor comes close to a metal or nonmetal object.

-Sonar (bindicator)

3d level sensors give an accurate indication of levels in grain bins, ignoring dust and changing levels on the top and sides, giving an accurate picture of the actual level in the bin.

-rotational sensor (whirligig)

a sensor that indicates whether or not a conveyor or other wheel is actually turning, and can also be used to measure how fast its turning or not. (underspeed)

Flow sensor

indicates how much material is flowing past a given point. Handy in pumping applications, especially for water/wastewater.

Process meters

Simple, easily adjustable controllers that can respond to variable input. When paired with an appropriate sensor, these units make easy work of level, flow, or rotational response and error detection.

Rugged, Sunlight-readable, and capable of operating in a wide variety of power and environmental situations, these controllers, make reliable, simple solutions viable at a low cost. Built in relays often further reduce cost of installation.

Simple Logic Controllers

For the slightly more complex operations taking in two or more sensor inputs, or combining multiple simple operations into a single operational base. Perfect for timed and time-sensetive operations, moderately complex monitoring needs, and simple systems integration. Once connected, they take the place of what would ordinrily be several cabinets worth of relays, timers, and simple level controllers; in addition to being able to do some functions those can't.

Variable Speed Drives

For pumping, ventilation, vacuum generation, and other situations where the system has to be highly responsive, or slightly overengineered yet capable of running with a more moderate energy use; a variable speed drive is the premier solution. Taking the energy in and outputting it to the motor system at the precise needed rate, this system can be governed by a simple sensor, combination of sensors, operator input, or other stimuli.
