Product Introduction

The JC-SBWZ Series Explosion Proof Pt100 Temperature Transmitter is an integrated industrial temperature measurement device with a local LCD display, Pt100 RTD sensor and built-in temperature transmitter.

The Pt100 Class A sensing element measures the process temperature, while the transmitter converts the signal into a standard 4-20mA output with HART communication for connection to PLC, DCS and other industrial control systems.

The transmitter is housed in a flameproof Ex db IIC T6 Gb enclosure for industrial hazardous-area applications.

The sensing assembly uses a Φ8 × 0.9 mm 316 stainless steel protection tube with an internal Φ5 mm mineral-insulated (MI) armored core.

A 1/2" NPT adjustable compression fitting allows the insertion position to be adjusted during installation.

The local LCD display provides convenient on-site temperature reading while the 4-20mA + HART signal supports remote monitoring and configuration.

Selection Guide

Step 1 — Specify the temperature range.
Provide the minimum, normal and maximum process temperatures. Confirm that the sensor and transmitter are suitable for the required operating range.

Step 2 — Select the sensor.
Specify Pt100 and the required sensor accuracy class. If a different sensor or wiring arrangement is needed, confirm availability before ordering.

Step 3 — Confirm the installation dimensions.
Provide the required protection tube length, insertion length and adjustment range. Confirm the reference point used for each dimension.

Step 4 — Confirm the connection.
Specify the process fitting thread and electrical connection separately. Provide the applicable thread standard and size to avoid installation mismatch.

Step 5 — Define the signal interface.
Confirm 4–20mA output, HART communication, power supply and compatibility with the receiving control system.

Step 6 — Confirm site safety requirements.
Provide the hazardous-area classification and required certification. Ensure that the complete instrument configuration is suitable for the installation location.

FAQ

Q1: What does the JC-SBWZ measure?

A: It measures process temperature using a Pt100 RTD sensor and converts the sensor signal into a standard output for monitoring and control.

Q2: Does it have a local display?

A: Yes. The listed configuration includes an LCD display for local temperature indication.

Q3: What output signal does it provide?

A: The listed output is 4–20mA with HART communication. Confirm the required interface and power supply when ordering.

Q4: What is the difference between Pt100 Class A and transmitter accuracy?

A: Pt100 Class A describes the sensor accuracy class. Transmitter accuracy describes the performance of the signal-conversion electronics. They are separate specifications and should be checked independently.

Q5: Is the insertion length adjustable?

A: The product information lists an adjustable insertion range of 0–150 mm and a nominal insertion length of 50 mm. Confirm the dimensional reference and available adjustment range for the selected configuration.

Q6: Is the transmitter explosion-proof?

A: The listed explosion-protection marking is Ex db IIC T6 Gb. Confirm the applicable certificate, equipment marking and installation requirements before use in a hazardous area.

Q7: What information is required for a quotation?

A: Please provide the temperature range, sensor type, output signal, process connection, electrical connection, protection tube length, required insertion length, power supply and hazardous-area requirements.
