It preserves the integrity of critical safety systems and ensures effective maintenance up to Safety Integrity Level (SIL) 3. The unit delivers discrete position control and predictive diagnostics. Intelligent alarms pinpoint the root cause of problems and predict necessary valve maintenance. The transmitter provides noncontact position digital feedback via highway addressable remote transducer (HART) 7 and dynamic synchronous transfer mode (DTM) protocols.
Free-Chlorine Analysis System Requires No Reagents
The amperometric free-chlorine analysis system analyzes water samples disinfected with chlorine without costly reagents and the accompanying required maintenance. The panel-mounted system includes a digital amperometric free-chlorine sensor and a digital pH probe mounted in an integrated flow assembly. A lead-free regulator sets system pressure at 15 psi. The pH-compensated measurement ensures accurate N,N-diethyl-1,4 phenylenediamine sulfate (DPD) verification, and a separate 1/4-in. sample valve enables a DPD verification test for residual chlorine without interrupting system measurement. A needle valve in the flow assembly maintains flowrates between 30 L/hr and 120 L/hr, and an inductive low-flow alarm switch indicates when flow is too low for proper measurement. The analyzer employs U.S. Environmental Protection Agency (EPA) Method 334.0 for the determination of residual chlorine in drinking water using an online analyzer.
Probe Reliably Measures Vaporized Hydrogen Peroxide
Hydrogen peroxide is used extensively in biodecontamination and sterilization applications, and the repeatability of measurements is important to achieve reliable verification of biodecontamination. The HPP272 probe measures vaporized hydrogen peroxide with high accuracy and repeatability. The device also measures temperature and humidity, both relative humidity and relative saturation. The probe incorporates a Humicap sensor that was developed for measurement of relative humidity and a Peroxcap sensor that was developed for measurement of hydrogen peroxide. The Peroxcap sensor uses an algorithm and heating function that prevent water from condensing on the sensor, which ensures reliability even in high humidity. In addition, the sensor has a purge function that helps maintain measurement accuracy between calibrations and extends the operating life of the probe. This function heats the sensor rapidly to remove possible impurities.
Metal Detector Identifies Contaminants in Vacuum-Filling Lines
The HDS pipeline metal detector identifies ferrous, nonferrous, and non-magnetic stainless-steel contaminants in applications such as food processing and inspection of high-viscosity liquids. It detects non-spherical contaminants such as metal clips, wire, swarf, and slivers introduced during grinding processes. It is constructed of stainless steel and can be integrated with vacuum fillers and other processing equipment. The detector is sealed to Ingress Protection (IP) 69K, which enables it to withstand stringent wash-down regimes in food processing plants. The short length of the throughput tube and use of zero-metal-free zone technology minimizes uneven distribution of fats toward the outside of the product, and enables metal fittings and other process equipment to be located close to the detection head without compromising detector performance.
Portable Magnetometer Detects Ferrous Particulates in Grease
