AP91 micro pressure sensor and transmitter is an industrial measuring instrument that is modular in design and meets global OEM standards. The micro pressure transmitter is stable and reliable, and has excellent cost performance. The micro pressure transmitter is rugged and durable to meet the requirements of more stringent industrial standards. The micro pressure transmitter is widely used in industrial support; industry support and equipment support. The series includes a variety of options, which are applied to different industries and different working conditions. The micro pressure sensor solves the needs for economic pressure monitoring in different occasions and serves a wide range of industries.
AP91 is a micro pressure sensor and transmitter for measuring dynamic and static pressure integrated transmission output. The micro pressure transmitter is suitable for applications where the installation space is limited or the weight of the sensor is light. The sensor of the AP91 micro pressure sensor and transmitter are made of a fully temperature-compensated Wheatstone bridge diffused on a highly stable micromachined silicon strained substrate; so the product guarantees good performance, the sensor body structure is compact, the outer casing can be made of titanium material, the weight without cable is less than 52g; and the G3/8 flat membrane design choices ensure the dynamic frequency response of 3KHz. The conventional small thread pressure can also reach the dynamic characteristic index of 1KHz; has a wide range of application scenarios, cost-effective.
