Introduction SP Series Pressure Transmitter The SP Series of pressure transmitters are designed to measure the level or pressure of various industrial processes. Models can be mounted with various threaded or flanged process connections. All models are available with 4..20mA (2 wire) output (or voltage outputs). The SP/FA line coms with an integrated Zero and Span adjustment.
Mounting Notes 1) Use PTFE tape or o'rings to seal the system. Transmitters with cable gland: Tighten the cable gland as much as possible so that the cable is securely in place and cannot be pulled through the cable gland. This will help insure that no moisture is able to infiltrate into the housing.
Installation Pressure of the Liquid Column Water Column System MKgfs System MKS P(mH2O)= relative density.h(m) P(Kgf/m2)= Specific Gravity(Kg/m3). h(m) P(KPa)= density(Kg/m3). g(m/s). h(m) Max. Principle of Operations 4...20mA The weight of the column of liquid Pressure generates hydrostatic pressure on the diaphragm of the sensor.

Fig. 4 Membrane infiltrating into the transmitter (Fig 5). Flange Use a cable with vent tube for all Sitron transmitter Seal models so that the linearity of the output signal and the operation of the unit is not compromised (this special cable can also be provided by Sitron) (Fig.
Calibration SP98FA and SP96FA Before the calibration of the unit is first tested, the process should be free of pressure or (if that is not possible) the unit should first be tested outside of the vessel. Make sure the muliti-meter is correctly connected in series with the source and the instrument.
Handling Seal the thread with Teflon tape before Fig. 1 installation. Do not turn or handle by the housing (Fig. 1). When tightening the sensor, use only use the 316S.S. hexagon fitting to achieve a seal, do not twist with the body of the sensor. (Fig.
