CAPACITIVE SENSORS WITH BLUETOOTH SAFELY DETECT MANY MATERIALS
Bluetooth capacitive sensors of the 26 series from Rechner have a hemispherical active surface for level control of products with a dielectric constant as low as 1.1 εr. The sensors detect products such as: bulk materials, like plastic granules, powder, cereals, feedstuffs; liquids, like water, juice, wine, oil, chemicals, or pharmaceutical solutions; pastes in the food processing industry, liquid gels, resins, or glue. The Bluetooth control function provides for greater sensor sensitivity, optimal sensor adjustment, and deposits on the sensor surface. Housing material is PTFE and a special version with flange is available. Sealing can be made with a gasket or PTFE-tape. Communication is via an Android mobile app.

VOLTAGE OUTPUT PRESSURE TRANSMITTER
The STS ATM.1ST is an electronically compensated pressure transmitter provides a 3-wire, analog voltage output. Available from SRP control systems, the transmitter offers accuracies of ≤ 0.05%FS or ≤ 0.1%FS including linearity, hysteresis, repeatability, zero and span setting errors. The transmitters utilize piezoresistive silicon sensor technology. The modular construction is said to provide manufacturing flexibility. Applications for the devices include test and measurement, industrial process monitoring and control, and test benches and calibration. Typical Total Error Band is ≤ 0.3% FS, compensated temperature-40° to 255°F, and full-scale ranges from 1 to 15,000 psi. Gauge, absolute or sealed gauge are available, as well as two output signal ranges. www.srpcontrol.com

Cameron Instruments has announced that Ebro offers a broad range of high accuracy thermometers with fixed probes or probes with cable and hand grip, available both blunt and pointed. The model TFX420/430 provides RTD accuracy up to 0.05˚C (-50˚ to 200˚C) in an impact resistant, waterproof package. The lithium battery provides a life of approximately 5 years and is customer replaceable. Units include an easy-to-read display with min./max. and hold functions for temperature, the company says. The temperature measurement range of -100˚ to 500˚C makes them suitable tools for process monitoring, temperature regulation, and core temperature measurement.
