655A series 316L stainless steel liquid pressure
transmitter
product manual:
Range down to 3 inches of water column, NIST traceable 6-point calibration
The 655A series 316L stainless steel liquid differential pressure
transmitter is used for differential pressure monitoring in high static pressure occasions. It is especially suitable for OEM equipment. It can be used for measuring ranges as low as 3 inches of water column under very high overpressure. The accuracy reaches 0.25%.
The 655A series
transmitter uses advanced technology to ensure the balance of high and low pressure ports. The automatic welding manufacturing technology makes it reliable and durable in long-life applications. Each product comes with a NIST six-point calibration certificate.
The 655A series differential pressure
transmitter is a fully welded 316 stainless steel material. It does not use any O-rings in the design. It is especially suitable for high static pressure applications and applications that can not be leaked.
