Ammonia (NH3) monitors is a microprocessor-based analyzer. It is used as an ammonia ion-selective probe. This compact, self-contained analyzer provides effective measurements of ammonia in sewage treatment, rivers, potable water treatment, boiler feed water and industrial effluents. It is a ammonia measurement device. It achieves better than 1 ppb detection of ammonia in ambient air. It advances detection limit and measurement speed to enable real-time monitoring of airborne ammonia in lithography areas.

High Level controllers monitor, regulate, and control liquid or solid levels in a process. There are three basic types of control functions that high-level controllers can use. The limit control works by interrupting power through a load circuit when the level exceeds or falls below the limit set point. A limit controller can protect equipment and people when it is correctly installed with its own power supply, power lines, switch and sensor.

Analog Indicators are mostly meters that indicate the value of the measurand on a calibrated scale by means of a pointer. The permanent magnet moving coil indicators are used as end devices in instrumentation systems for the indication of the amplitude of the primary measurand. The scale calibration may not always be linear and hence accuracy in reading becomes poorer in portions of the scale where it is cramped.

Analog Panel Meters are instruments that measure variables such as pressure, flow, temperature, speed, current and voltage. They display values on a dial with a moving pointer or needle. Analog panel meters are available with one or more channels and measure one or more variables in different units. Analog panel meters measure single or three phase power. Analog panel meters feature a range of measurements such as 0 - 4 mA or 0 - 10 VDC.

Analog Pressure Gauge consists of two circular shaped, convoluted membranes sealed tight around their circumference. The pressure acts on the inside of the capsule and a pointer indicates the generated stroke movement. Pressure gauges with capsule elements are more suitable for gaseous media and relatively low pressures. It combines both a chemical seal and a pressure gauge into one unit. A metal pushrod welded to the top of the diaphragm transmits the deflection of the diaphragm to the linkage.

Analog Remote transmits operating power and 0-10 Vdc analog signal from a single BAW analog sensor. The transmission is from 0 to 10 vdc analog signal between remote units. These can operate with or without batteries.

Analog transmitter is a field-mounted device that senses a physical parameter such as pressure or temperature and generates a current proportional to the measured variable in the standard range, 4 to 20 mA. Providing the output as a current in a twisted-pair loop has many advantages. The measurement signal is insensitive to noise and is not affected by changes in loop resistance. The transmitters meeting the standard are interchangeable and the power required to energize the transmitter circuits can be derived from a remotely supplied loop voltage.

Analog Transmitters are used when a 4-20 mA signal is desired. Analog transmitters measure humidity and temperature. Analog transmitters provide signal conditioning, amplification and a corresponding digital or isolated analog output signal for tank/bin/hopper weighing systems. Analog transmitters are flexible, high-performance devices for use with all strain gage-based transducers.

Analog vacuum gauges are devices for measuring vacuum or sub-atmospheric pressures. It uses different technologies such as manometers are made of a transparent U-shaped tube and filled with a liquid such as water, mercury or oil. It requires an analysis of display & scale types and scale units. Analog vacuum gauges features signal outputs and communication protocols. It includes temperature measurement outputs to prevent measurement errors due to changes in temperature.

Analog metric cameras are often used for taking aerial images to get a high resolution. Therefore this camera is analyzed offline with a scanner. The image is scanned with a high resolution. The strategy is very time consuming and requires much memory. These cameras in conjunction with an offline scanning process are applied by the taking of aerial images, because these images often have the size of 23 x 23 cm2.

An analyser is a device that analyses given data. It examines in detail the structure of the given data and tries to find patterns and relationships between parts of the data. An analyser can be a piece of hardware or a software program running on a computer. It can also be an instrument or device which conducts chemical analysis on samples or sample streams. Such samples consist of some type of matter such as solid, liquid, or gas. Many analyzers perform such analyses automatically or mostly automatically, such as autoanalyzers.
