Gefran has a novel combined pressure and temperature indicator for plastics manufacturers.

Gefran has a novel combined pressure and temperature indicator for plastics manufacturers.

40TB dual-channel indicators are designed to be used with melt pressure transducers and temperature sensors on plastic manufacturing machinery.

Input 1 is for strain gauges and pressure transducers.

Input 2 is for thermocouples, RTD, PTC, NTC, 0-60mV, 12-60mV, 0-1V, 0-5V, 1-5V, 0-10V, 2-10V, 0-20mA or 4-20mA.

Sample time is 15-120ms and accuracy is 0.2% at full-scale.

There is no need to change any hardware or use external shunts to go from one type of input to another, users simply change a parameter on the input configuration menu.

To manage nonlinear sensors, there is a 32-element custom linearisation of the main input.

The front panel, with IP65 protection rating, has a dual four-digit display (one for pressure and one for temperature) each with 13mm high red LEDs, a keyboard with three function keys and a fourth key that can be configured as, hold, alarm reset, and set change functions.

These functions can also be assigned to an optional digital input.

The 40TBs hardware allows it to have up to four outputs.

The wide selection includes relay, logic and analogue outputs.

RS485 serial communications is available as an option.

The device is supplied in an "easy" configuration with just a few simple software parameters.

For programming, the "Winstrum" PC configuration kit configures the entire device in seconds, saves programs, prints data, displays trends and saves historical data.
