Schaumburg, Ill.— The E8M line of pressure sensors is available in positive, negative, and differential pressure. The cylindrical positive and negative devices measure 1.08 × 1.22 × 1.48 in., while the differential version measures 1.69 × 1.02 × 0.75 in. The extremely compact sensors are also lightweight, making them ideal for installation on robot arms and other movi...
Milpitas, Calif. —UltraStable silicon micromachined chip has increased the performance over a broader temperature range of the TO-8 Series pressure sensors. Temperature errors are improved to 0.5% full scale output over a range of –20 to +85 °C. These solid-state piezoresistive pressure sensors are available in 6- and 8-pin packages and standard ranges of 0-15 and 0-250 psi.
Rice Lake, Wis. —CB-1 concrete batch controller provides dual-scale control in a single automated concrete batching system. Two weight indicators—one for each hopper—gather weight data used to control the release of four separate aggregates and two cements. The system also controls water addition and six admixtures by monitoring a pulse from a flowmeter.
This is the third installment of a five-part series on Process Sensing. Pressure sensing appeared in March. Smart sensors appeared in May. Other articles include flow measurement (September) and level sensing (November).Unsung. Unremarked. Easily forgotten but definitely indispensable. They come in a myriad of sizes and packages.
Warminster, Pa.— The EBTH is an addition to the Bailey-Fischer & Porter HART family of transmitters and is interchangable with the EQS transmitter. Inputs include RTD, thermocouple, millivolt, and ohms. The user-configured output can be linear with respect to a selected temperature span, or follow a user-programmed function generator.
Georgetown, Tex. —Model 310 Gas Flo-meter features both an LED bar graph display and an LCD digital readout. The 2.5-in tall bar graph meter is visible from up to 20 ft. Model 310 is designed to measure gas flow rates from 10 ml/min to 200 liters/min over several ranges with an accuracy of ±3% full scale.
Phoenix, Ariz.— Series 900 Smart Pressure Transmitters feature flush mounting for applications where clogging is often a problem. According to the manufacturer, the flush-mount devices are suited for use in pulp and paper operations. They are also intended for applications that involve slurries, suspended solids, or materials that may crystallize, polymerize, or precipitate.
This is the second installment of a five-part series on Process Sensing. Pressure sensing appeared in March. Others include temperature sensing (June), flow measurement (September), and level sensing (November).If you really want to stir up some controversy in the control room or up in the engineering department, get on the subject of smart sensors.
Horsham, Pa. —SLT II is an RF/Admittance smart level transmitter incorporating Honeywell's Digitally Enhanced protocol. Released by Drexelbrook Engineering Co., the new design features upgraded software and a new housing. The electronics can be mounted integrally with the sensor or remotely from the sensor.
More users worldwide are installing smart actuators and positioners as they realize their higher-level controls need increasingly consistent valve performance. This new emphasis is pushing valves to become more fully integrated into users' digital control systems, according to Automation Research Corp.
