AC-operated LVDTs are designed for a wide range of position measurement applications. These are rugged hermetically sealed sensors, constructed entirely of stainless steel, and intended for general industrial use. AC-operated LVDT signal conditioners receive AC current or AC voltage as input signals. They excite a transducer according to defined parameters for voltage and frequency. A variable gain differential amplifier receives the resulting signal, which is then coupled to a synchronous detector, multi-step filter, analog-to-digital converter, and micro-controller. The AC LVDT requires onboard oscillator, carrier amplifier, and demodulator circuitry for externally. The AC LVDT is able to tolerate extreme variations in operating temperature from -40 to + 120 degree C. The AC LVDT advantages include greater accuracy and a smaller body size.

AC-powered RS-232/RS-485 converters RS-485 repeaters are operated on the AC power supply. It converts RS232 signals to those required by RS485 at all standard baud rates from 300 to 115.2K baud. Internal control circuitry automatically controls the flow of data on the RS485 bus. This module transparently repeats RS485 signals at all standard baud rates from 300 to 115.2K baud. Internal control circuitry automatically controls the flow of data on the RS485 bus.

AC/DC Capacitive Proximity Sensors operates with 20...253 VAC or 20...300 VDC. They are available in 034mm smooth barrel, metal, PBT or complete PTFE housings & shielded or non-shielded models. All units are switchable from normally open to normally closed with a simple turn of a screwdriver on the rear of the sensor. It features switching frequency of 25Hz (AC) & 40 Hz (DC), 2 meter cable or quick-disconnect, IP 67 rated, short circuit protected, overload protection and an operating temperature rating from -10 to +70°C (+14 to 158F).
