Weighing Systems || P-RTN Compact Ring-Torsion Load Cells P-RTN

Features:

 

PTB & OIML approved as suitable for trade use (up to 5000 d and 75010 d in case of multi-divisional scales)

High accuracy, even for very small utilisation ranges (down to  15% in case of trade use according to OIML)

High output signal and, thus, high-resolution of useful signal  range

Low power consumption allows realisation of multiscale

 systems with simple evaluation electronics

Protection to EEx ib IIC T 6 for use in explosion hazardous areas

Protection class IP 68

 

Application

 

Acting as a transducer, the load cell

converts the mechanical input signal,

the load, proportionally into the

electrical output voltage.

The consistent optimization of

the ringtorsion load cells offers

additional advantages:

The extremely low headroom

simplifies the use in almost all

weighing applications.

The sturdy design enables easy

transport, installation, and operation,

even under very harsh

environmental conditions (e.g.

aggressive media, interfering

forces, or extreme temperatures)

Construction

● Hermetically sealed due to laser welding; protection class IP 68

● High corrosion protection due

to the use of electrolytically

polished stainless steel

  All electrical components are

inside the load cell and are

thus optimally protected

● The high-quality, sturdy connection

cable is lead radially

into the load cell

● The P-RTN load cells are

compatible with earlier ring-torsion

load cells if our adapter kits are used

Functions

● High measuring sensitivity

● High repeatability

● High long-term stability and, thus,

continuing and consistently high

accuracy

● Minimal effect on accuracy by

side forces

● High reliability and availability,

even in case of unavoidable

shock loads, constraining forces

or electrical interferences

● Integral excessive voltage protection

● Moment-free load input/output

due to direct, vertical force flow
