Page 5: Chapter 1. Description
Chapter 1. Description 1-1. General The Pneumatic Transmitter (Model K_P), in conjunction with respective type of detector (meter body), is used to detect and transmit a process pressure, differential pressure, liquid level, or specific-gravity. This manual covers the structure and maintenance of the transmitter itself and adjustment of the transmitter coupled with the meter body. -

Page 8: Chapter 2. Operating Principle
Chapter 2. Operating principle The input for the transmitter is applied as a torque through the torque tube. The torque causes the gap between the nozzle and flapper to change. The gap change causes the back pressure of the nozzle to change. The back pressure is boosted in both pressure and capacity by the pilot relay in order to be used as an output air pressure. -

Chapter 3. Installation and operation 3-1. Installation The transmitter (Model K_P) is installed in the state that it is coupled to a detector (meter body). Installation and connection to the process is done by means of the meter body. For installation, refer to the operator’s manual of the meter body used in conJunction. -

Page 12: Chapter 5. Calibration And Adjustment
Chapter 5. Calibration and adjustment 5-1. General The detector (meter body) feeds a torque, which is proportional to the measured process variable, via the torque tube to the transmitting mechanism of the transmitter. Therefore, regardless of the type of the meter body, the transmitter should be adjusted so that it transmits an output signal of 0.2 to 1.0 kgf/cm linearly proportional to the 0 % to 100 % measuring range. -

(8) If the output pressure is shifted from 100 %, adjust the SPAN ADJ boss at the bottom of the feedback bellows as follows: If the output is higher than 100 %, turn the boss so that the output becomes lower than 100 % by an amount of 1/4 of the shift. -

5-4. Calibration of absolute pressure transmitter (Refer to procedure of 5-3.) To calibrate a transmitter which has a vacuum measuring range alone or which has a compound measuring range including a vacuum range at a substantial rate, use such devices as vacuum pump and needle valve for the variable pressure source. - Page 16 Warranty period and warranty scope 1.1 Warranty period Azbil Corporation’s products shall be warranted for one (1) year from the date of your purchase of the said products or the delivery of the said products to a place designated by you.
