ifm PT5400 Pressure Transmitter, 0 to 400 bar, 4-20 mA

ifm PT5400 Pressure Transmitter, 0 to 400 bar, 4-20 mA

The ifm PT5400 is a compact pressure transmitter for high-pressure systems: 0 to 400 bar with a 4 to 20 mA output, a stainless steel housing and a G 1/4 external thread. The pressure rating is 1000 bar and the burst pressure is at least 1700 bar, so it is built for hydraulics and other duty where surges are frequent. The sensor body is only 19 mm in diameter and 66 mm long, which suits tight manifolds.

With IP67 and IP69K protection and a medium temperature down to -40 degrees Celsius, the PT5400 is also used on mobile and outdoor equipment. Seven Star LLC supplies the PT5400 in Oman and the GCC as an independent supplier; quote PT5400 when requesting an offer.

PT5400 technical specifications

The table lists the values published by the manufacturer for the PT5400. Where a parameter has several operating modes, the headline value is shown; the full parameter list is in the manufacturer documentation.

How the PT5400 works

The PT5400 turns process pressure into a standard 4 to 20 mA loop signal. The measuring element deflects with pressure, the on-board electronics correct for non-linearity and temperature, and the output current rises in proportion to the applied pressure across the span. A two-wire style current loop is immune to voltage drop along the cable, so the controller sees the same value at the end of a long run as at the sensor. There is no display and no menu, so commissioning is mostly a matter of wiring, scaling the analogue input in the PLC and verifying the zero point with the line open to atmosphere.

Where the PT5400 fits and related parts

The PT5400 is an analogue transmitter without a display. If you need local indication and switching points in the same housing, the PN7092 (0 to 100 bar) is the display alternative at a lower range, and the PX3224 (0 to 100 psi, NPT) is the ceramic-cell option for low pressure. The PT5400 supplies a signal to a PLC analogue input or a loop indicator.

Selection and ordering checklist for the PT5400

Work through the points below before you confirm the order, so that the PT5400 you receive is the one your machine or plant needs.

• Confirm the span: 0 to 400 bar relative pressure
• Check wiring: 8.5 to 36 V DC with a 4 to 20 mA output, so loop load must be within the maximum load for your supply
• Check the G 1/4 external thread against the mating port and its FKM sealing arrangement
• Verify that your medium is compatible with 17-4 PH stainless steel at the wetted side
• Decide on cordset type for the 2-contact M12 connector

The manufacturer lists this article under the type designation Pressure transmitter, PT-400-SEG14-A-ZVG/US/ /W. The article number PT5400 is the reference to quote when ordering, and the type designation is useful for technicians who compare the label on an installed unit.

Installation, commissioning and maintenance

Mount the transmitter in a position where the pressure port drains and no trapped air or condensate can sit on the measuring element. Use the sealing method that matches the thread type, observe the tightening torque, and avoid strain on the connector. When commissioning, power up, confirm that the output reads close to 4 mA at zero gauge pressure, then scale the PLC input to the span of the sensor. A periodic zero check and a visual look at the cable and connector are sufficient maintenance. In systems with hydraulic shock or pulsation consider a restrictor in the port, which protects the element and calms the signal.

Because the sensor is rated for 60 million pressure cycles at 1.2 times nominal pressure, typical machine duty is not a life problem, but pressure peaks beyond the range should still be damped. Torque the port within the recommended 25 to 35 Nm. In loop wiring, check that the supply voltage minus the sensor minimum gives enough headroom for the connected load.

Typical applications in Oman and the GCC

Typical uses include hydraulic power packs on valve actuators and wellhead control panels, hydraulic presses and test rigs, high-pressure cleaning and injection pumps, and mobile machinery. The IP69K rating and temperature range help in washdown and in desert heat, and the compact housing fits manifold blocks.

Pressure instruments in the Gulf face heat on sun-exposed skids, fine dust and salty humidity. Stainless steel wetted parts, a sealed M12 connection and a conservative pressure margin are the three things that decide service life. Mount the sensor out of direct sun where possible and keep the connector pointing down.
