Description
The WPCK07 pressure transmitter features a diffused silicon core as its pressure-sensitive element. An internal dedicated integrated circuit converts the sensor's millivolt signal into a standard current signal, allowing for easy connection to computer interface cards, control instruments, smart meters, or PLCs. Long-distance transmission can be achieved via current output. It is compact, lightweight, and features a fully sealed stainless steel structure, enabling operation in corrosive environments. The product is easy and simple to install, possesses extremely high vibration and shock resistance, and is widely used in fire protection, process control, automotive, medical equipment, HVAC, and other fields. The built-in circuit board is a network-type transmitter board with an RS485 interface.
Through highly integrated circuitry centered on a microprocessor, it reliably acquires and processes pressure signals and provides RS485 communication output. The communication interface enables fully digital debugging and calibration.

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, but the module will be 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 sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
