Enclosed in a standard 1/4-DIN watertight housing, the model 3679N features two on/off relays for pH or ORP, automatic-temperature-compensated (ATC) pH readings, and a shorting plug selectable to pH or ORP. It also has selectable hysteresis settings for customized control and isolated 4–20-mA current output that can be used as a proportional output. The operating ranges are 0.00–14.00 for pH (with an accuracy of ±0.03 pH units) and –1,999 to +1,999 mV for ORP (with an accuracy of ±0.1% full scale).

The explosion-proof Logix 3200IQ and the intrinsically safe 500si series use piezo technology and inner-loop feedback to quickly set up and calibrate diaphragm- or piston-operated valves without additional handheld devices, software or configuration/ calibration tools. The 500si series is available in two models — the 510si for analog applications and the 520si, which, like the 3200IQ, uses the HART communication protocol.

CalPoint combines a vortex shedding flowmeter and temperature transmitter in a single instrument. Repeatability is ±1% of actual flow and ±0.25% of actual temperature; accuracy is ±2% of flow. Temperature range is 32°F to 210°F, and readings can be displayed in either Fahrenheit or Celsius. The meter is available in pipe sizes ranging from 3/4 in. to 2 in. for flowrates of 2.5–200 gal/min.

Flowrates of high-viscosity, non-abrasive fluids can be measured and controlled by the positive-displacement flowmeters and batch controllers comprising the HPD Series. Accuracy is ±0.5% at low flowrates, even under changing viscosity conditions.They utilize stainless steel gears and bearings, and the bodies are made of Type 303 or 316 stainless steel or high-strength aluminum. These units are available in 1/4-, 1/2- and 1-1/4- in. NPT port sizes for flows ranging from 0.003 to 120 gal/min, and can operate at pressures up to 5,000 psi and temperatures up to 400°F.

The intrinsically safe ISS-105 IS Super Cell can operate as a controller for eight different pumping configurations where duplex, triplex, quadplex and duplex SPS (separate pump stop) pumping methods are possible. It can indicate low, high and out-of-sequence alarms, and has a variablelag pump delay setting. When used as a five-channel relay, all five channels can be set to positive or negative logic with the possibility of two latched relays, and the fifth relay can be configured as a delay-on-make or delay-on-break output with variable time delay.

The wMPC Series controllers provide up to seven zone controllers in a single wall-mounted package. Input type can be individually configured for each zone from the keypad. Thus, a single unit can accommodate multiple sensor types (temperature, pressure, velocity, flow, volume, etc.) at the same time. Each zone has its own ramp and soak profile or a manual setpoint. Several control modes are available (on/off, PID and heat/cool), as well as multiple display modes.

The UT551 digital indicating controller allows users to acquire temperature, pressure and flowrate data and to make changes to controller settings via an Ethernet connection. It employs the Modbus/TCP protocol and is equipped with a 10BASE-T interface. A gateway function allows a PC or other host system to access non-Ethernet-enabled indicating controllers or peripheral devices by simply connecting them to the UT551.

The RC Series Mobile Powered Workstation is ergonomic, compact, and has onboard power to run a laptop computer, a printer, and a scanner or other device for at least 8 h of normal use. The unit has an 18-in. storage compartment and an upper laminated work surface that measures 20 in. by 22 in. with a ¼-in. lip on all sides. It is constructed of 11-gauge steel and has fully reinforced surfaces. The rechargeable battery offers integrated, seamless power.

Parts made from Kalrez Spectrum 0040 — the latest member of the company’s Kalrez family of materials — are available for chemical and hydrocarbon processing applications. Seals, hose couplings and other parts made from this material resist leaks and chemical attack from a broad array of aggressive chemicals and solvents at temperatures ranging from 220°C to –42°C.

The ability to reduce fouling and sludge buildup from hot oil and thermal fluids can increase pump life, and improves heat transfer and plant efficiency. The use of cleaner fluids can help to reduce wear on moving parts such as mechanical seals, impellers and valves, helping to reduce unscheduled downtime and overall maintenance requirements. The Vector Series Model VB10C Thermal Fluid Filtration System continuously filters heat transfer fluids using economical glass-fiber-wound cartridges, removing contaminants down to 10 mm.
