Product Description:
The Pacific Scientific PMB31B-20201-02 is a small, precise pressure sensor meant to be used in automation systems or hydraulic outflow control systems.
Available in 0-10 bar rating, it provides an analog output signal of 4-20 mA, thus giving the potential to integrate smoothly with PLCs and controllers as well as monitoring equipment. The sensor has an M12, 4-pin electrical connection that is powered with 10-30 V DC. It has a G1/4-inch process connection, which is standard in the majority of industrial systems, and thus installation is quite simple and solidly compatible. The wetted components have been made of stainless steel 316L, which possesses superior resistance towards corrosion and is compatible with various process media such as hydraulic oils, water, and light chemicals. The PMB31B-20201-02, with very fast response down below 2 milliseconds, is good to use in dynamic pressure monitoring, where quick response in feedback is critical. It is IP67-protected, that is, resistant to dust ingress and temporary submersion in water, making it suitable to use in extreme business environments.
It functions stably at temperatures of –20°C to +80°C, and can withstand up to 20g of vibration between 20Hz to 2000 Hz, proving very durable in high-movement or high-vibration environments. Its accuracy is within ±0.25% of full span, taking into account non-linearity, hysteresis, and repeatability, which guarantees steady and consistent readings throughout its measurement range. It also has a long-term drift of ≤ ±0.2% of the upper range limit/year, providing flexibility for longer recalibration and reduced maintenance costs. The servo motor weighs 130 grams and offers a dynamic combination of size, power, and durability. Its functionality makes it perfect for pressure monitoring in applications requiring precise control.
