Overview
The MK-20S-DT is a high-frequency dynamic pressure transmitter for capturing rapidly changing pressure signals. Ranges from -0.1 MPa up to 100 MPa are available, covering vacuum through high-pressure hydraulic measurement.
Key Features
- High-frequency response for dynamic and pulsating pressure
- Ranges selectable from -0.1 MPa vacuum up to 100 MPa
- Stable output for pressure Peaks, ripple and transient capture
- Compact stainless construction for industrial environments
Applications
Hydraulic system testing, pulsation analysis, engine and compressor development, leak testing and laboratory pressure research.

Frequently Asked Questions
What makes a transmitter ‘high-frequency’?
Its sensing element and electronics are optimized for very fast pressure changes, so short pressure peaks and pulsations that a standard transmitter would smooth out are faithfully reproduced.
Which range should I choose?
Select the smallest range that still covers your maximum pressure including spikes — this gives the best resolution. Ranges from -0.1 MPa to 100 MPa are available.
