Keyence AP-13 Pressure Sensor

The Keyence AP-13 Pressure Sensor is a positive pressure sensor head designed for industrial pneumatic and fluid monitoring systems, commonly installed in hydraulic equipment, air pressure lines, and automated production machinery to ensure accurate pressure control. Part of the AP Series (AP-V80), it provides gauge-pressure measurements from 0 to 1 MPa (0 to 145 psi) with repeatability of ±0.5% of full scale. It uses a 1/8 NPT / R(PT)1/8 connection port and carries IP67 protection for use in harsh environments. The unit features a stainless steel pressure port (TYPE304 / S17400), weighs about 120 g, and is rated for pressure resistance up to 2.0 MPa with an operating temperature range of -10 to +70°C. Typical applications include monitoring and controlling positive pressure in pneumatic and fluid systems across manufacturing lines, hydraulic systems, and automated equipment where stable pressure supports consistent process performance. Common replacements include AP-13S, AP-13SK, and AP-14S.
