4-20mA temperature transmitter with display

PRODUCT INTRODUCTION

RTD sensors
As the Pt100 is an RTD sensor, let’s look first at what an RTD 4-20ma temperature sensor is.
The abbreviation RTD comes from “Resistance Temperature Detector.” It is a temperature sensor in which the resistance depends on temperature; when temperature changes, the sensor’s resistance changes. So, by measuring the sensor’s resistance, an RTD sensor can be used to measure temperature.
RTD sensors are most commonly made from platinum, copper, nickel alloys or various metal oxides.
PRT Sensors
Platinum is the most common material for RTD sensors. Platinum has a reliable, repeatable and linear temperature-resistance relationship. RTD sensors made of platinum are called PRT, “Platinum Resistance Thermometer.” The most common platinum PRT sensor used in the process industry is the Pt100 sensor. The number “100” in the name indicates that is has a resistance of 100 ohms in 0°C (32°F) temperature. More details on that later.

WIRING DIAGRAM & DRAWING

A temperature transmitter is an electronic device that sends a temperature measurement over two wires to the processing unit. It converts the small electrical signal from the temperature sensor into a more readable signal for the processing unit.

4 20ma temperature transmitter are an essential part of the industry. They convert input signals from sensors such as resistance thermometers, thermocouples, and potentiometers into a consistent analogue or digital output signal. These sophisticated

devices have the capability to provide two-way communication, assisting in device diagnostics, sensor configuration and measurement range customization, as well as error signaling and identification of measuring points.

A temperature transmitter interfaces a temperature sensor with a display or control device. By translating a non-linear millivolt signal from the sensor into a linear milliamp signal that can be sent longer distances without degrading, they are able to

make more accurate measurements as well as providing a platform for digital communication.

Temperature transmitters for all industrial applications
A temperature transmitter with display converts a temperature sensor or thermocouple signal into a stable and standardized output signal. Digital transmitters offer more than just precision measurement: they are intelligent, flexible, and offer high measurement

accuracy. Your process can be safer and more efficient when they are part of the measurement chain.
