Boiler Follow Mode: The boiler is divorced from the generation control, which means the steam turbine utilizes stored energy in the boiler to provide immediate load response. The boiler must then change firing rate to bring pressure back to setpoint.
Turbine Follow Mode: Turbine control valves maintain a set pressure while the boiler fires to maintain load. Drawback here is a slower generation response. There are variations with this scheme, in that the turbine control valves can be fully opened at higher loads to minimize the energy penalty associated with the DP loss across them. In that case, it has been called sliding-pressure control, or even cascade control.
Coordinated Control: In general, you provide various logic schemes to move the steam turbine valves for quick load response, as well as fire the boiler for the anticipated energy requirements of the boiler (generally via an energy balance equation).

In many applications, higher-accuracy
measurements are required to protect
the customer from over-billing and the
supplier from under-billing. Common
products requiring this level of accuracy
are typically oils, fuels, edible oils, and
alcohols. In the oil & gas industry, this
requires a system called automatic
tank gauging (ATG) as defined by the
American Petroleum Institute (API)
standards.
PBZ Series Intelligent Bi-Polar Power Supplies
The PBZ series is a bipolar type DC regulated power source that can continuously change both + and – polarities passing through 0 without changing the output terminal.
By adopting a “Switching + Linear” system, the PBZ is able to realize both drastic weight reduction as well as high speed and low noise operation. Since operation covers 4 quadrants, power can be both supplied (source) and absorbed (sink). The PBZ can also drive inductive or capacitive loads. The unit also equips a signal generator function which enables waveform and sequence creation. The PBZ is also capable of synchronized operation which is required for voltage variation tests, and it can also be expanded for large current applications through master-slave parallel operation.
The 6247C/6247G is a DC voltage current source/monitor designed for evaluating high voltage semiconductors and LED luminaires that demand high efficiency and low power consumption, capable of outputting voltage up to +250 V and current up to ±320 mA. It provides high accuracy of ±0.02 % with 4½-digit source resolution and 5½-digit measurement resolution.
The 6247C/6247G features the well-established VSIM, ISVM, sweep and pulse generation functions. Also, leak current measurement up to 10 pA is possible. In addition, it is equipped with the various types of sweep functions such as linear, fixed, random and two slope linear sweep functions, the pulse measurement function with the minimum pulse width of 50 μs, the micro voltage and current measurement function with the minimum resolution of 10 μV or 10 pA, and the suspend function that controls the optimized output status. By using these functions, the 6247C/6247G can be widely used for evaluating or testing semiconductor and other electronic components in R&D fields and production lines.

The HiVol 3000 particulate sampler performs remote unattended sampling of PM2.5, PM10 or TSP along with basic meteorological parameters.
The HiVol 3000 incorporates advanced programming functions and electronic volumetric flow control to maintain a consistent flow and collect a truly representative sample of particulate matter.
Optional attachments allow the sampler to measure wind speed and direction which can then be used to trigger sector selectable sampling (e.g. fence-line monitoring).

Inspect solar panel bypass diodes for opens and shorts in broad daylight without covering panels
INSPECT SOLAR PANEL BYPASS DIODES FOR OPENS AND SHORTS IN BROAD DAYLIGHT WITHOUT COVERING PANELS
Traditionally, bypass diodes can only be inspected for good working condition at night or when power is not being generated by the solar panels in order to verify that any applied current is guided past the solar cells.
With the FT4310, you can detect for open faults even when the sun is out without covering the panels.
Testing can also be performed at night.
*Testing for short-circuit faults can only be performed during the day.
