Analog Input Products
Analog input boards are useful for measuring variably changing conditions in the real world. When we want to measure these variably changing conditions, we need analog inputs to convert these changing real world conditions to changing electrical quantities. For example, monitoring the temperature inside a wood kiln, or the water pressure on the output of a pump, or the heart rate of a medical patient. In each of these cases, you can use one of our analog input devices to convert the electrical data from a sensor or transducer into binary data that can then be used by your computer. The device that converts this data is known as an analog to digital converter (abbreviated ADC, A/D, or A to D). An analog input is a measurable electrical signal with a defined range. The analog input changes continuously in a definable manner in relation to the measured property. This data is very useful for process monitoring, process control, or simple monitoring / data collection and acquisition. ACCES' analog input boards amplify and multiplex input signals from thermocouples, strain gauges, accelerometers, photo sensors, flowmeters, RTDs, thermistors, voltage sources, millivolt sources, and current sources, just to name a few.

High Resistance Neutral Grounding Devices
HRG systems limit the fault current by placing high resistance between neutral point of transformer (or generator) and ground. As it is not possible to locate the fault point in delta connected systems, an artificial neutral point is created and delta connected system can be grounded. This allows a fault current of a few amperes thus locating the fault point gets easy. When the neutral point is grounded thru high resistance, both continuity of operation is provided during fault condition and sufficient current (typically between 2 A and 10 A) flow is provided for ease of locating the fault point.

200 Ampere Micro OHM Meters
HL-200
Measuring the line loop contact resistance by bridges is not the ideal method as the test current is only a few milli amperes. Thus the value is not the true value of the contact resistance. Model HL- 200 is a direct reading tester, and uses a test current of 200A DC, resulting in true value and accurate measurements. Model HL- 200 adopts digital circuit technique and is used for measuring contact resistance of switch control equipment at test current of 200A DC. The measurements are accurate as the test is highly stable. HL- 200 is a new, fully automatic micro controlled tester that measures contact resistance at 200A DC with built in printer.

Array Antennas
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves radiated by each individual antenna combine and superpose, adding together (interfering constructively) to enhance the power radiated in desired directions, and cancelling (interfering destructively) to reduce the power radiated in other directions. Similarly, when used for receiving, the separate radio frequency currents from the individual antennas combine in the receiver with the correct phase relationship to enhance signals received from the desired directions and cancel signals from undesired directions. More sophisticated array antennas may have multiple transmitter or receiver modules, each connected to a separate antenna element or group of elements.
