The latest in a family of 10-loop powered instruments, the LPB bar graph can be configured for 1, 3 or 5 pointers or full bars. The LPB is 4–20-mA powered and only puts a 4.5-V burden in the loop, allowing for multiple units in the loop on the factory floor. The 51 segments of its light-emitting diode provide 2% resolution and accuracy indication of the loop’s value, and can be scaled within 30% of its factory setting of 0–100% via the front panel zero and span pots.
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.
