Automotive 12V-HID lamp inverter circuit based on TL494
The TL494 is a fixed frequency pulse width modulation circuit that includes all the functions required for switching power supply control. It is widely used in single-ended forward double-tube, half-bridge, full-bridge switching power supplies. Main features: 1. Integrated pulse width modulation circuit. 2. The chip has a built-in linear sawtooth oscillator with only two external oscillating components (one resistor and one capacitor). 3. Built-in error amplifier. 4. Stop the 5V reference voltage source. 5, can adjust the dead time. 6, built-in power transistor can provide 500mA drive capability. 7, push or pull two output methods.
Explosion Proof Transmitter Turbine Flowmeter
Turbine Flowmeter with explosion proof transmitter means that a Turbine flowmeter matches an explosion proof transmitter and, at the same time, the turbine flowmeter adopts some explosion proof measurement when in the production process, and meanhwhile the transmitter and electrical interface are also stainless steel and can withstand certain explosion impacts.
A turbine flowmeter with an explosion proof transmitter is usually used in those sites where the measured air other gas contains some exposure hazard gas element. Adopt a turbine flowmeter with explosion proof transmitter can prevent the hazard level on one side, and in the other hand, once the explosion occurs, a turbine flowmeter with explosion proof transmitter can reduce the explosion hazard result.
