The old saying “if it ain’t broke, don’t fix it” cautions against tampering with something that performs reliably and regularly proves its worth. Arguably, this advice applies to the circuit design ...

The TMZ Dual (2TPRG) PC-Programmable MODBUS Temperature Transmitter from Moore Industries allows users to increase density and reduce costs with dual RTD, thermocouple, mV, resistance or potentiometer ...

The circuit in Figure 1 generates acurrent source that is ratiometric tothe voltage reference. The ADC usesthe same voltage reference to provide aratiometric digital output. Over temperature,the ADC ...

The compact 10 x 8 x 6-inch NEMA 4X enclosure facilitates all of the electrical connections including the heating cable, the AC Power and the RTD Sensors. The unit features a high resolution TFT ...

Emerson announced the release of the Rosemount 3144S temperature transmitter, a new industrial measurement solution with the ...

The Rosemount X-well technology now allows for non-invasive temperature measurement up to 650 °C (1,202 °F) without the need ...

Download this article in PDF format. Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage ...

IC 1 is pin-configured to drive a constant current of 400 µA through the grounded sensor, T 1 . Driving T 1 with this level of current—“zero-power” operation—keeps the worst-case power that the ...

Of course, an increasingly common way to measure temperature is to use some form of smart sensor. A module or IC can use any of the methods we’ve talked about, convert it to engineering units ...

1. The ADG7421F dual SPST switch provides the critical function of protection from transient or static faults, including overvoltages up to ±60 V for sensitive signal and sensor inputs.
