Review DWYER 4b33 New

Introducing the Dwyer Model 4B-33 Transducer, a versatile and reliable sensor designed for level measurement applications in various industries. This 4B33 transducer is a part of Dwyer Instruments' extensive line of level measurement solutions, which are renowned for their accuracy, durability, and ease of use.

The 4B-33 Transducer is a buoyant, pressure type level sensor that utilizes a 4-20mA output signal. This transducer is suitable for measuring the level of liquids in open or sealed vessels, tanks, or containers. It is available in different materials such as 316L Stainless Steel, PVC, or Polypropylene, making it ideal for use in harsh environments and different process media.

This transducer features a unique design with a buoyant float that rises and falls with the liquid level, activating a switch when the float reaches the desired height. The switch then sends a 4-20mA signal to the control system, allowing for precise level monitoring. The switch has a repeatability of 0.1% of full scale and a hysteresis of 0.5% of full scale, ensuring reliable and accurate level measurement.

The 4B-33 Transducer is also equipped with a temperature compensation circuit, which maintains the accuracy of the output signal in temperatures ranging from 0 F to 122 F (-18 C to 50 C). It has a shock and vibration resistance of 10,000 G and 10 Hz, respectively, making it suitable for use in applications with high levels of mechanical stress.

The installation of the 4B-33 Transducer is straightforward and requires minimal setup. It can be used with various mounting options, including threaded, clamp, or magnetically mounted floats, to accommodate diverse application requirements. The device is also easy to calibrate, with a built-in calibration feature that allows for adjustment of the output signal with a simple push of a button.

In summary, the Dwyer Model 4B-33 Transducer is a robust, accurate, and versatile level measurement solution that is well-suited for various industries and applications. Its unique design, reliable performance, and ease of use make it a top choice for engineers, technicians, and operators seeking precise and dependable level measurement capabilities.
