Industrial Control Panels and Instruments

Temperature and Pressure Controllers form a large part of Process control Instrumentation. Then you have Flow, Humidity and many more custom parameters.

All Real Life Physical Phenomena are reduced to Analog Numbers by Sensors and Transducers. This analog value is amplified and linearized and brought into standardized windows like 1-5 Volts or 4-20mA and more.

These Analog Values go to Analog Closed Loop Controllers or Meters for Measurement and Control. In Embedded Controllers, the Analog is converted to Digital ( At least 12 bit, 8 bits are cheap not used for industrial automation, more than 16 bits is not required as sensor accuracy/linearity never transgress such precision )

Embedded Process Controllers may use Microcontrollers with Floating Point Arithmetic, Lookup Table, Logic and Basic Math. Advanced Controllers may use DSP and Complex Algorithms for Adaptive control. (self learn, fuzzy logic.).

There is a instruction sheet for a 3 wire transmitter. It Amplifies the uV signals from a K type Thermocouple, Chromel-Alumel. The output is a strong 4-20mA which is fit for looping and driving a Controller an Alarm and an Analog Recorder too.

8 Bits D/A may be used when a control signal is needed, like 4-20 mA Control Output driving a Thyristor PWM bank. Here 8 Bit is enough when the thyristor bank drives large heaters. The thermal inertia and delay makes very precise control nearly impossible.

When a parameter needs to be controlled in a tiny area, precision control is possible. A 16 Bit control signal is required. The system/thermal design here is more important than the controller, they have to be tandem for obtaining repeatable precision control.

Test & Measurement Instruments by delabs

These are Instruments that Jack built. Here read Jack as me, delabs. Some were hand made, some in the form of workflow of a small firm with professional equipment. Some made in quantities, other a couple or more for R&D.

Test and Measurement is all about Measurement or Metrics. Without this, every other part of electronics becomes like boneless entities.

Instruments i designed and built. (long ago).

Wireless Gigabit Alliance – WiGig 60 GHz

Interconnects Devices and Computers on WiGig technology for High Speed Media Rich DataCommunications. Multi-gigabit wireless communications using the unlicensed 60 GHz spectrum.

Wireless Gigabit Alliance – WiGig 60 GHz

“The Wi-Fi Alliance and the Wireless Gigabit Alliance (WiGig Alliance) today announced a cooperation agreement for multi-gigabit wireless networking” – Wi-Fi & WiGig cooperate

WiGig Certified Multi-gigabit, low latency connectivity. Coming in 2016.

WiGig Certified Multi-gigabit, low latency connectivity.

WiGig version 1.0 specification Includes data transmission rates up to 7 Gbps. Backward compatible with the IEEE 802.11 standard.

The WiGig specification will allow devices to communicate without wires at multi-gigabit speeds. It enables high performance wireless data, display and audio applications that supplement the capabilities of today’s wireless LAN devices. – WiGig at Wikipedia
