The WPCK89 digital output pressure transmitter is a new generation of intelligent digital products, characterized by high precision, high reliability, convenient use and installation. The product has a wide voltage range, low power consumption, and multi-level protection design, with strong anti-interference ability. The standard IIC bus has a maximum speed of 400K, a collection rate of 50 times/second, a power consumption of less than 2mA during operation, and a standby current of 1uA. The standard IIC communication protocol makes this transmitter particularly suitable for computer control systems.

The pressure seat of WPCK89 digital output pressure transmitter is processed with a single piece integrated structure of 316L stainless steel or 17-4PH stainless steel, with high overload performance. Its pressure interface has no welds, silicone oil or other organic substances, and good sealing performance. The sensitive components of the sensor are firmly sintered on the pressure seat using glass micro melting technology, greatly improving the high temperature and vibration resistance of the sensor, ensuring the long-term stability, reliability, and durability of the transmitter in harsh industrial environments. In the standard purification production process, all parameters are strictly controlled, and the entire product has undergone strict testing and aging screening of components, semi-finished products, and finished products, with stable and reliable performance.

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
