CST-TST Pressure Transmitter

This compact pressure sensor integrates a 4-digit segment LCD display with a switching / analog output stage, combining accurate diffused-silicon pressure sensing with a rugged 316L stainless steel wetted section and a 304 stainless steel display housing. It is designed for reliable pressure monitoring and control in industrial, hydraulic and pneumatic systems. • 4-digit segment LCD display • Adjustable PNP / NPN switching output • Normally open / normally closed selectable • Relay output option • Multi-point high-precision calibration • Push-button setup for fast, convenient configuration • Display head rotatable 345° for optimal viewing angle

Advantage

The sensor shares the same design philosophy as CST’s broader pressure instrument range, emphasizing durability, safety and ease of on-site operation:

  • Robust structure designed to withstand overload conditions
  • Rotatable display module with front push-buttons for convenient on-site parameter setting
  • High-strength metal housing suitable for demanding industrial environments
  • Strong resistance to transient voltage surges, protecting the internal electronics
  • External button operation that does not compromise the enclosure protection rating
  • Modern, compact appearance combined with dependable manufacturing quality
