Ideal for characterizing spherical, irregularly shaped and acicular (needle-like) fiber particles, agglomerations, or mixtures, the family of EyeTech particle-size and image analyzers has a size channel that employs a unique laser obscuration method that yields direct and true single-particle-size measurements. It also has an image-analysis channel that uses dynamic and/or static methods. Accurate and easy to set up, the units feature: size ranges of 0.1–3,600 µm; dynamic range of 600:1; and a high resolution of 0.33% of full scale (min. 0.2 µm).

The Type 8055 full-bore magflowmeter permits precise, highly accurate dosing/filling control across a wide array of flow applications. The continuous or batch control Type 8055 incorporates two transistor outputs (40-VDC, 100-mA), 0/4–20-mA current output and RS485. The flowmeter is available in three versions — general-purpose (ANSI or wafer flange), low-flow (NPT) and sanitary (Tri-Clamp). Measuring range, orifice-size range and fluid-temperature range, respectively, for the: general-purpose version are 3.2–1,233 gal/min, 1–4 in.

Enclosed in a heavy-wall, stainless steel housing, the HSE/HSER 750 Series of 3/4-in.-dia. DC-operated linear-variable-displacement transducers (LVDTs) are impervious to dirt, water, steam and other corrosive elements. The units are ideal for use in hydraulic-cylinder positioning, valve-position sensing, automatic assembly equipment and other industrial applications with hostile conditions.

An economical alternative for applications that don’t require the most-demanding detection limits, the DF-745 Nano Trace moisture analyzer offers a low-detection limit (LDL) of 2 ppb. The device uses tunable diode laser absorption spectroscopy (TDLAS) technology and features: an accuracy of greater than ±3% of reading or ±1 ppb; a typical response speed of 10 min; and an upset recovery time of less than 5 min.

Capable of handling demanding water flow measurements, the Marsh Single-Mag flowmeter requires little maintenance and is easy to install and use. Equipped with a unique electromagnetic technology, the device serves in pressurized line applications from 2 in. to 96 in. It has a flow accuracy of ±2% of reading and operates over a wide flow range, from –5 to 20 ft/s. The Single-Mag provides a reliable 4–20-mA analog output signal for monitoring and alarming. The flowmeter can also measure pressures up to 250 psi and temperatures up to 160°F in stainless steel pipes.

The NQL series of loop-powered instruments is now 10CFR50-B-qualified (a Nuclear Regulatory Commission requirement for nuclear power plants). The NQL consists of eight models that accept 4–20 or 10–50-mA input and displays the process variable in digital or digital/bargraph mode. Both LCD and LED versions are available and some models come with RS232E I/O. The new series is intended for replacement (or new installations) of analog meters where only the two-signal wires are available (no power source). The LCD versions come with automatic tricolor backlight.

Designed for macromolecular characterization, the Triple Detector gel-permeation chromatography/size-exclusion chromatography (GPC/SEC) system features an integrated triple detector array (TDA) comprised of a unique low-angle light-scattering (LALS) detector, four capillary viscometer detectors; a GPCmax pump, autosampler and degasser module; and OmniSEC software for multiple detection analysis and complete system control.

A new low-range differential pressure (DP) sensor option has been added to this firm’s One Series electronic switch product line. With all stainless-steel wetted parts and welded diaphragms, this rugged DP sensor measures in low pressure ranges, including 0–5, 0–50, 0–100 and 0–200 psid. Sensor profiling and temperature compensation provide 0.5% accuracy, 0.1% repeatability and excellent media compatibility. Approvals include UL for Canada and the U.S. (cULus), as well as ATEX approvals for Europe.

The Series I-2 immersion temperature assemblies are designed to lower installation costs associated with temperature monitoring of hot and chilled water, condensed water, or low-pressure steam applications. The assembly comes complete with a 6-in.-length Type 304 stainless steel probe and a polycarbonate enclosure. These units are designed to install directly and easily into a thermowell or 1/2-in. saddle fitting. Models are available with a Pt 100 ohm  RTD sensor or Pt1000 ohm RTD sensor for increased accuracy and reliability.

The MT5200 level transmitter is designed for use in challenging bulk-solids applications. A concentric waveguide directs the radar beam, alleviating divergence problems and echoes in tanks with narrow openings. Unaffected by dust or feed flow, the MT5200 accurately measures materials with dielectric constants as low as 1.3 and bulk densities up to 50 lb/ft3. It can operate at temperatures and pressures up to 400°F and 1,500 psi.
