Product catalog summary

Technical Specifications:
The document outlines the technical specifications for the ECT/ECTR/ECTN series used in industrial and refrigeration applications. The mounting torque is specified between 15 to 20 Nm. The operating temperature ranges from -25°C to +85°C, with media temperature varying based on the model: ECT supports -25°C to +125°C, while ECT 400bar/5000psi and ECTN 400bar/5000psi support -10°C to +125°C and -10°C to +85°C respectively.

Electrical Connections:
The document details various output and load resistance configurations. For example, a 4-20 mA output requires a supply voltage of 9-30 VDC, while a 0-5 VDC output requires a load resistance greater than 2.5 kΩ and a supply voltage of 10-30 VDC. The document also specifies the pin configurations and ingress protection ratings, such as IP65, IP67, and IP68.

Pressure Connections:
Various pressure connection types are described, including G3/4" and G1/4" with specific dimensions and sealing requirements. The document provides detailed measurements for each connection type, ensuring compatibility with different industrial setups.

Instructions and Type Label Description:
Instructions for mounting and electrical connections are provided, emphasizing the importance of following guidelines to ensure proper operation. The type label includes information such as the type code, serial number, measuring range, and manufacturing date.

Additional Notes:
The document reserves the right to make alterations as technical progress warrants, indicating ongoing updates and improvements to the product line.
