(NewTek: San Antonio) -- NewTek Sensor Solutions now offers hermetically sealed 4-20mA sensors that accept long cables for process control and factory automation applications when standard lengths cannot reach distant control rooms, signal conditioners, PLCs, and data loggers. The robust analog 4-20mA current loop output enables the use of longer cables from a sensor to a control system without electromagnetic interference or noise interrupting the signal and operation of associated equipment. Unlike voltage, the current does not degrade over long connections. Recalibration to correct for voltage drop due to cabling impedance is also unnecessary.

As sensor cables transmit data and signals from a transducer to control units, they must be resistant to outside elements. NewTek offers heavy-duty, industrial shielded cable with resistance to noise, vibration, moisture, and spills. Available in custom lengths up to 100 ft, cables that carry a 4-20 mA signal are less vulnerable to outside movement and noisy environments typical of packaging and assembly lines. Users can also use their own cable assemblies in lengths up to 1,000 ft or more. The sensor can be placed on the manufacturing floor with cable running to the control room to provide output.
