SUP-PE100 Compact Pressure Transmitter
The SUP-PE100 is a compact diffused-silicon pressure transmitter for gauge, absolute or sealed pressure from −100 kPa to 60 MPa, in accuracy classes 0.2, 0.25 or 0.5. It has a 316L wetted diaphragm, EPDM or FKM seals, outputs from 4–20 mA to 0.5–4.5 V and RS485 Modbus, and a T90 response of 10 ms or less. It is designed for data center liquid cooling, HVAC and pump skids.
What it does
Liquid-cooling equipment needs pressure sensing in tight spaces: across pumps, filters and heat exchangers, and at rack manifolds. The PE100 fits that space while matching the electrical interfaces OEMs already use, from ratiometric voltage to Modbus.
For general industrial use Supmea offers the SUP-P300 (IP68 option), and for flow and level by differential pressure the SUP-2051 series.

Frequently asked questions
Which output should I choose for a CDU controller?
Match the controller input. 4–20 mA is the most noise-immune over long cable runs; 0.5–4.5 V ratiometric suits 5 V OEM boards.
Gauge or sealed pressure?
Gauge references local atmosphere through a vent; sealed references a fixed internal pressure and suits high ranges or wet locations. See our pressure types article.
