Introduction
Characteristics
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. All units offer excellent stability,
repeatibility, accuracy and temperature compensation. HART communications protocol
is also available for many models.
Each model in this series is offered in pressure ranges that are suitable for various types
of application requirements such as for; liquids, gases, areas with limited space, food
industry, chemical industry or areas that feature aggressive mediums or waste fluids with
varying degrees of suspended solids.
Technology
The SP series utilize the principle of the alteration of resistance or capacitance. The SP
Series is available with sensing elements of either 316 Stainless Steel, ceramic
piezoresistive diaphragms or thick filmed ceramic diaphragms (for more aggressive
mediums or applications).
The external pressure of the medium induces a dislocation of electrical load that
accumulates on the opposite surface of the diaphragm, resulting in an output signal that is
proportional to the pre-calibrated pressure range of the sensor. The electronics converts
this information into either a 4...20mA(2 wire) output signal (standard) or a 1 to 5V (3 wire
optional per custom order), which is directly proportional to the applied pressure of the
process.
Small, robust and easy to install
Reliable measurement of level and pressure.
HART Communications Protocol is available (for most models)
Available in a wide range of process connections: Threaded, Flanged or Sanitary
