- Stephen Woodward.. contributor Nick Cornford recently published a delightfully clever design idea ( Reference 1 ) using a platinum RTD calibrated to output a 1 mV/ C signal that’s perfect for ...Oct 1, 2024
- Stephen Woodward.. (without K. Kong’s complexity) is (mainly) the self-compensating TBH diode charge pump described in an earlier design idea: “Take-back-half precision diode charge pump” ( Reference 2 ). We’ll get to that ...Sep 30, 2024
- Alexander Bell.. shipping moving-coil meters, manufacturers may short-circuit the meters' terminals with a length of wire, which provides effective electromagnetic damping and results in better immunity to external mechanical vibration ...
.. and results in better immunity to external mechanical vibration and shocks that can occur during transportation. This Design Idea applies essentially the same principle to analog meters under normal operating conditions. Connecting a ...Sep 30, 2024 - Nick Cornford.. of 0 C. Choosing the currents carefully gives a bridge output of 1 mV / C. PT100 RTDs, which use (precisely doped) platinum wire or film, are defined to have resistances of 100 Ω at 0 C and 138.5 Ω at 100 C. Using identical ...
.. in pressure with height reduces water’s boiling point by about 1 for every 300 m increase. Check your altimeter and barometer and adjust accordingly. This ( Ref. 3 ) is a useful tool for doing so. Lastly, there is the DMM with ...
.. tell us that frustration increases drive. I was driven to produce the circuit in this design idea by my increasing frustration with a collection of digital thermometers, all of which claimed accuracy to ...Sep 25, 2024 - Mehmet Efe Ozbek.. circuits for dual-coil relays. Drivers usually include logic elements to make sure to energize only one coil at a time. The design in Figure 1 uses only two MOSFETs to drive a dual-coil RF relay. The N1810UL RF switch has dual 24 V coils ...Sep 24, 2024

.. levels in response to the corresponding digital states. Sometimes however, as Christopher Paul observes in the cited design idea (Part 1 of a 4-part series), they don’t. The mechanism behind these deviations isn’t ...Sep 23, 2024 - Stephen Woodward.. that meld the functions of sensor and heater into a single device: FET, BJT, or even a simple length of fine gauge copper wire. A virtue inherent in thermostat designs that use a transistor as combined sensor and heater is that independent ...
.. recent EDN design ideas, we’ve seen thermostat designs that meld the functions of sensor and heater into a single device: ...Sep 18, 2024 - Stephen Woodward.. short while back, I published a design idea ( Ref. 1 ) that uses a single linear pot to control the gain of a high performance OP37 decompensated ...Sep 3, 2024
- Dale Litwhiler.. drives a DS2423 pulse counter. A host PC or µC reads the output of the pulse counter via the Dallas Semiconductor one-wire bus ( Reference 1 ). The circuit uses approximately 150 µA of current, allowing the circuit to steal its ...
.. of these capacitors is 0.2 in. These dimensions provide a measurement range of 4 in. with a resolution of 0.2 in. This design uses 1 MΩ for the oscillator timing resistor, RC, because the timing resistance must be much larger ...Sep 2, 2024 - Peter Demchenko.. fuse described in this design idea does not drop the connection, it simply limits the output current. A behavior that is similar to a ...Aug 14, 2024
