Water Chemistry: Chemical Feed Controller

Challenge

Bring laboratory-grade water analysis and chemical feed control to large-scale commercial and industrial water cooling tower systems.

Solution

A custom designed, solid-state, highly accurate multi-channel fluorometer combined with a microprocessor-driven chemical feed controller.

Summary

Accurate chemical monitoring and feed control of chemicals in cooling tower water systems is required to reduce mineral scale, corrosion, and microbe growth. Relatively high volumes of expensive chemicals are required to protect these systems.

Product Design: Designing for Reliability and Manufacturability

Challenge

Refine a proof-of-concept design to optimize product reliability, compliance to regulatory standards, and manufacturability.

Solution

Develop a system of circuit boards and interconnections for cost effective integration and manufacturing while adhering to industry and regulatory standards.

Summary

Assessing the viability of a product idea can be difficult. The process often begins with a rough design sketched on paper. As the research and development phases of the project move forward, one or more proof-of-concept prototypes are often required.

MathCad Circuit Modeling: Improving Circuit Design

Challenge

Meet aggressive project schedules while reducing hardware development costs by improving the circuit design process.

Solution

The addition of detailed electronic circuit modeling in the latest release of the PTC MathCad software environment provides a powerful tool to simulate, optimize, and document the circuit design prior to building a PC board.

Summary

SPICE simulation alone will only report the performance of a circuit design, but it will not recommend component values to meet the design goals.

Industrial Monitoring & Control: Boiler Control

Challenge

Create a modular, expandable, configurable and robust boiler monitoring and control system that can be used world-wide.  The system must be able to connect to a wide range of external input sources as well as control external devices.  Ethernet, USB and modem connectivity are required.

Solution

An NXP 32-bit ARM7 processor, multiple Microchip 8-bit PICs, Micro Digital SMX operating system, ANSI C, and the IAR Embedded Workbench were used to create this extendable, robust, highly flexible system.

Summary

Tecnova was asked to build the next generation of industrial controllers for a long standing customer. The customer's goal was ambitious – configurable enough to support multiple current product lines as well as future products not yet envisioned.
