Sensor Bodies
-
The armature - assembled sensor body - is the central component of an inline photometer. We have already designed more than 1000 different sensor bodies and more than 50 types are always on stock. All optek inline sensor bodies are made from high quality materials and are machined with extreme precision. The quality-tested manufacturing tolerances allow optical path lengths of up to 1000 mm, for which the accuracy of the incoming and outgoing light beam is ensured by testing a laser-based coaxiality tolerance test to the reference axis. To cover a wide spectrum of different process conditions, optek sensor bodies can be manufactured from various materials (also for aggressive chemicals or with NACE MR 0175) and adapted with regards to:

Spectrum Analysis For E5081A Up To 20 GHz
S960904B
-
The Keysight S960904 spectrum analyzer (SA) software application adds high-performance spectrum analysis to the E5081A ENA-X up to 20 GHz. With fast-stepped FFT sweeps resulting from optimized data processing, the SA software application provides quick spurious searches over broad frequency ranges. The application enables simultaneous spectrum measurements using test and reference receivers. The multichannel SA pairs with the internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. The SA application uses source-power and receiver-response calibration and fixture de-embedding, providing highly accurate in-fixture and on-wafer spectrum measurements.

Frequency Synthesiser
RA062-F2
-
The RA062-F2 is a multiple LO module used to generate three pairs of LO signals, each pair being phase matched in order to provide the capability to drive two phase and amplitude matched, high sensitivity narrowband receivers such as might be required for an EW receiver system with DF functionality.The Stepped Frequency Synthesiser is based upon Direct Frequency Synthesis, DFS, whereby the 1GHz input reference signal is multiplied, filtered and mixed to generate a given number of isolated and filtered single tone CW signals from the 1GHz comb. A finely tuned signal is then generated using a multi-way switch to select between the 1GHz spaced CW tones and mixed with fine resolution signals generated using a custom DDS/VCO PLL network. In this way finely tuned signals can be generated between 7.5GHz and 23GHz.

1000W Ferroresonant Power Supply
Series PRR
-
Kepco's PRR are 1000 Watt rack mounted laboratory systems power supplies that offer the low cost and very high dependability of ferroresonant voltage stabilization.The ferroresonant stabilizing technique provides extraordinary isolation from a wide variety of source noise. It is inherently short-circuit proof and cannot expose delicate loads to overvoltage hazards. Hence no crowbar, fuses, or bounding circuits are needed. Ferroresonant power supplies use no noise-producing switches or oscillators. Voltage setting is independent of delicate control settings or diode references and requires no comparators, references, or limiters. Efficiency is 70-80%.

Lake Variable Area Flow Meters
-
Lake Variable Area flow meters, often referred to as rotameters, measure flow rate of a liquid or gas by relating linear displacement of an internal “float” or sharp-edged orifice plate (Lake) to a corresponding flow rate. As flow rate increases, the orifice area that the flow moves through also increases – thus, the term “Variable Area.” Variable Area meters either allow flow through a peripheral orifice formed between a tapered wall and a float as in the traditional rotameter, or an annular orifice and an internal tapered metering pin in the Lake Monitor.

Mid-Range Gas Filter Correlation Carbon Dioxide Analyzer
Model T360M
-
The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T360M comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.
