Miniature Low Pressure Flow-Through Sensors
The 26PC Series Miniature Low Pressure Flow-Through Sensors feature proven sensing technology that uses a specialized
piezoresistive micromachined sensing element to offer high performance, reliability, and accuracy.
Each sensor contains four active piezoresistive elements in a Wheatstone bridge configuration. When pressure is applied,
the resistance changes and provides an output signal in mV proportional to the input pressure.
The low power, compensated, unamplified Wheatstone bridge circuit design offers 1 psi through 100 psi sensing ranges
in a variety of pressure port types and termination configurations. The mV output is available in both negative and positive
voltage.

format.
These sensors are intended for use with media compatible with plastics and media seals specified in the Nomenclature
and Order Guide (see Figure 2). (2D drawings also provide plastic housing and port material information.) They are designed
and manufactured according to ISO 9001 standards.

1Span is the algebraic difference between the output signal measured at the upper and lower limits of the operating pressure range, where
Port 2 (P2) > Port 1 (P1).
2The output signal obtained when zero pressure is applied to all available ports.
3The maximum deviation of product output from a straight line fitted to the output measured over the specified operating pressure range, calculated
according to BFSL. The straight line is fitted along a set of points that minimizes the sum of the square of the deviations of each of the points (“least-
squares” method),
4The maximum deviation in offset due to changes in temperature over the compensated temperature range, relative to offset measured at a reference
temperature of 25 °C.
5The maximum deviation in span due to changes in temperature over the compensated temperature range, relative to full-scale span measured at a
reference temperature of 25 °C.
6Repeatability is the maximum difference between the output readings when the same pressure is applied consecutively, under the same operating
conditions, with pressure approaching from the same direction within the specified operating pressure range. Hysteresis is the maximum difference
between output readings when the same pressure is applied consecutively, under the same operating conditions, with pressure approaching from
opposite directions within the specified operating pressure range.
7Overpressure is the maximum pressure that may safely be applied to the product for it to remain in specification once pressure is returned to the
operating pressure range. Exposure to higher pressures may cause permanent damage to the product. Unless otherwise specified, this applies to all
available pressure ports at any temperature within the operating temperature range.
