Product Brief：

Introduction

SAND manufactures a complete series of standard and tailor-made melt pressure sensors with different filling materials for various extrusion applications at processing temperature of up to 550℃. SAND sensors feature their proprietary properties of non-mercury technology and upgraded functions which are absolutely user-friendly specifically for food and medical industries and the hazardous environments of the extrusion and polymer processing industries. Optional auto-zero function for local or remote configuration and integrated safe relay switch for excess pressure protection. SAND sensors are also interchangeable to Dynsico,Gefran and Gneuss etc.
