Plug and play temp sensors
Infosense-P plug and play sensors improve the accuracy of thermocouples by three times, RTD sensors by 10 times, the vendor claims. They provide a high level of accuracy and convenience through automatically linking the customer’s application to the vendor’s NIST-traceable calibration lab. The sensors incorporate an EEPROM memory chip, preprogrammed with each sensor’s part number, manufacturing information, and full range temperature calibration. Using IEEE 1451.4 technology, when a sensor is wired or connected to IEEE 1451.4 compatible electronics, the controller accesses the information provided and performs a full high-order curve fit to correct for all known error.

Colorimeter inspects
The stand-alone, handheld CR-400 is a colorimeter that measures samples, compares to targets, displays data, stores up to 1,000 readings and interfaces with a PC or the vendor’s DP-400 processor. It offers pulsed Xenon, d/0° measurement geometry, plus choice of 8mm or 50mm aperture models. It measures color using up to six user- or industry-specific color indices, and reads color and color difference for 14 standard color scales.

Temperature and humidity sensor
The HS-2000 sensor combines capacitive-polymer sensing technology with a novel measurement method, eliminating the need for temperature correction and calibration by the user. The factory-calibrated sensor, which includes a thermistor and circuitry to correct for temperature and calculate true relative humidity, provides both humidity and temperature outputs and is accurate to +/- 2%. The digital version, priced at less than $20 in volume, communicates via an RS232 link. Analog versions are available with a 4-20 mA or 0-5 volt output.

Keep an eye on wastewater
The 3300 series ultrasonic flow monitoring system provides high-accuracy flow measurement especially for water treatment and wastewater streams. The use of Doppler ultrasound technology and advanced spectrum signal processing measures the entire flow stream. It operates from a 9 VDC power source or AC power using a converter, plus there’s an optional solar panel. A vandal-resistant dual-password system allows for local or remote downloading of data.

Gripping temp probes
Six new temperature probes have been added to the SureGrip line. Designed for plant and laboratory technicians who use digital thermometers, the new line includes probes for taking measurements of air, liquids, large surfaces, small areas and insulation-covered surfaces. The 80PK-22, for instance, is an immersion temperature probe for use in liquids or gels, is compatible with K-type instruments, and has a range from -40° to 1090° C.

Instant surface temps
ThermoTrace waterproof low-temp infrared thermometer, Model 15006-40, is completely waterproof (IP67 compliant) and can be washed and sanitized. It is especially well suited for uses in the food industry because of its temperature display range, -40° F to 428° F (-40° C to 220° C), useful for instant, surface temperature screening of food during hot holding, in chilled displays and refrigerated storage for HACCP and food safety procedures. It is also a diagnostic tool for refrigeration technicians, and can be used to read temperatures of moving parts or to check surfaces in hard-to-reach places. Features include normal or continuous reading mode, a memory function that holds up to 99 points of temperature data, and a 15:1 field of view with laser sighting of an object as small as 2.6 inches.

Non-intrusive level gauge
The non-intrusive design of the MagnaStar magnetic liquid level gauge provides accurate level readings while protecting operators from high pressure and high-temperature fluids in a tank, process vessel or boiler. The rugged design minimizes operating costs by eliminating downtime due to leaks or required maintenance. The gauge has no glass tube to replace or multiple gaskets to maintain. The two-color indicator, easily read from a distance, is mounted on the gage chamber but completely isolated from the process fluid.

Portable hygrometer
The Hygro-Thermometer is a small, portable, multifunctional data logger that can take up to 15,000 humidity, temperature, dew point and wet bulb measurements. Time- and date-stamped data is available in list or graph form using the supplied Windows-compatible software. The meter provides real-time measurements of two customer-selected parameters on its large LCD display. It’s suitable for monitoring any space where these measurements are critical, including many food plant applications.

Make sense of oxygen
OxySense 4000 is a noninvasive oxygen measurement sensor with built-in processor and automatic infrared temperature sensor. Using optical technology, it measures oxygen concentrations within containers, bottles and packages without puncturing or destroying the seal. Multiple measurements can be made over time on the same package, producing more accurate results with fewer containers and at a lower cost, making the system ideal for R&D, quality control and shelf-life studies. It is fully portable and self-contained, has an integrated 8.4-in. display and standard PC keyboard and mouse.

Measure powder granules
The Powder Flow Analyzer is a system for accurately measuring the flow properties of powder granules and wet mixes. It helps manufacturers of food and nutraceuticals to avoid common problems such as batch and source variation of ingredients, caking during storage, bridging in hoppers and sticking during production. Rapid analysis of ingredients, blends and finished products, as diverse as flours, dried fruits, pulses, herbs and milk powder can be measured. The patented blade causes controlled flow and can be mathematically described, negating the need for complex torque measuring systems.
