Force Sensor / Pressure Gauge for Mold Box Clamping Systems

Product Specifications

Technical details and manufacturing context for Force Sensor / Pressure Gauge

Definition

This force sensor or pressure gauge is a component used in mold box clamping systems to monitor the clamping force or hydraulic pressure applied during the molding process. It provides real-time data to ensure that mold halves are held together with the precise force required for proper material flow and part formation, helping to prevent defects such as flash or short shots. The device is available in two primary variants: force sensors, which convert mechanical force into an electrical signal using strain gauges or piezoelectric elements, and pressure gauges, which use a Bourdon tube or diaphragm to mechanically displace a pointer on a calibrated dial. The product is designed for industrial environments and offers a rated pressure range of 0–60 MPa, with an accuracy of ±0.5% FS per IEC 60770. It provides a standard 4–20 mA output signal and operates on a 24 V DC supply (±10%). The operating temperature range is -40 to 85°C, and ingress protection is rated IP65–IP67 per IEC 60529. Wetted parts are made of 316L stainless steel (ASTM A240), with an overpressure limit of 150% FS and burst pressure of 300% FS. Response time is ≤1 ms, and weight ranges from 0.5 to 2.5 kg. Process connections are available in G1/4 to G1/2 sizes per DIN EN ISO 228-1. Materials on file include stainless steel, alloy steel, and silicon. This directory entry provides reference specifications; actual model values and standards must be verified with the legal manufacturer or supplier before procurement.

Working Principle

The device operates by converting mechanical force or fluid pressure from the clamping mechanism into a measurable signal. Force sensors typically use strain gauges that deform under load, changing electrical resistance, or piezoelectric elements that generate a charge proportional to force. Pressure gauges use a Bourdon tube or diaphragm that deflects with pressure, moving a pointer on a calibrated dial. The electrical signal (4–20 mA) or mechanical displacement is then displayed or transmitted to a control system for monitoring and adjustment.

Frequently Asked Questions

What is the rated pressure range of this force sensor/pressure gauge?

The rated pressure range is 0–60 MPa. This range should be selected to cover the maximum clamping force with a safety margin. Confirm the exact range for your application with the manufacturer.

What output signal does the sensor provide?

The standard output signal is 4–20 mA, which is a common industrial current loop suitable for long-distance transmission. Verify compatibility with your control system.

What is the ingress protection rating?

The ingress protection is rated IP65–IP67 per IEC 60529, indicating protection against dust and water. Choose a higher rating for dusty or wet environments.

What materials are used for wetted parts?

Wetted parts are made of 316L stainless steel (ASTM A240), which offers corrosion resistance for aggressive media. Other materials on file include alloy steel and silicon, but confirm the specific material for your process media.
