Rosemount 1151 Pressure Transmitter

With the help of our team of experts, our company known as a leading Exporter, Distributor, Supplier & Trading Company of Rosemount 1151 Pressure Transmitter in Tanggu, Tianjin, China.
The accuracy of a flow, pressure, or level measurement depends on proper installation of the transmitter and impulse piping. The piping between the process and transmitter must accurately transmit process pressure to the transmitter. Mount the transmitter close to the process and use a minimum of piping to achieve best accuracy. However, keep in mind the need for easy access, safety of personnel, practical field calibration, and a suitable transmitter environment.
In general, install the transmitter so as to minimize vibration, shock, and temperature fluctuations.
The Rosemount 1151 Pressure Transmitter weighs 12 lb. (5.4 kg) without a meter and 15 lb. (6.8 kg) with a meter. This weight must be securely supported. The transmitter is calibrated in an upright position at the factory. If this orientation is changed during mounting, the zero point will shift by an amount equivalent to the liquid head caused by the mounting position. For Smart Transmitters, follow a Because a zero trim must be zero-based, it generally should not be used with Rosemount 1151 Smart Absolute Pressure Transmitters. Absolute pressure transmitters reference absolute zero. To correct mounting position effects on a Rosemount 1151 Smart Absolute Pressure Transmitter, perform a low trim within the full sensor trim function.
