Indicating Controller is Ethernet-Enabled
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.

Controllers Accept a Variety of Temperature and Process Inputs
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.

Relay Controls Multiple Pumps
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.

Flowmeters and Controllers Handle Viscous Liquids
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.

Flow and Temperature Measurement in One Unit
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.

Positioners Set Up and Calibrate Valves Quickly
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.

pH, ORP Controller is Watertight
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).
