ISEN – Temperature Transmitter

The ISEN-JCTT Series Smart Temperature Transmitter is a high-performance device specifically engineered to meet the demanding requirements of industrial environments. Featuring versatile signal processing capabilities and HART communication, this product is the ideal choice for your enterprise’s professional temperature measurement applications.

Product Overview

The ISEN-JCTT Series is a 2-wire temperature transmitter that accepts input signals from a wide variety of sensors, including Thermocouples (T/C), RTDs, Ohm, and mV signals. The device provides a 4-20mA output signal integrated with the HART communication protocol, allowing for flexible configuration and calibration.

Key Features

• Versatile Input Signals: Supports a wide range of thermocouples (K, S, B, E, J, T, R, N) and resistance temperature detectors (CU50/PT100, 2/3/4-wire), as well as mV and Ohm signals.
• High Accuracy: ±0.1% of full scale.
• Long-Term Stability: ±0.1% of full scale over 2 years.
• Fast Response Time: Output signal update time of just 90ms.
• HART Communication: Supports HART protocol for remote configuration, calibration, and diagnostics.
• Easy Calibration: Zero point and span can be calibrated via HART communication or directly using the integrated keypad. Features a one-push button for automatic zero point calibration.
• Backlit LCD Display: A multi-angle rotatable, backlit LCD screen displays the measured value (5 digits) and a 0-100% bargraph.
• Direct Configuration: Allows for direct parameter setup via the integrated keypad.
• Robust Design: Features an explosion-proof and weatherproof housing.
• High-Quality Materials: Wetted parts are available in SUS304/SUS316/Hastelloy C/Tantalum. The housing is made of low-copper cast aluminum alloy with a polyurethane paint finish.
• Isolation: Input/output/ground isolation up to 480VDC.
• Vibration and Interference Resistance: Vibration effect is only ±0.05% of URL per g up to 200 Hz. Complies with SAMA PMC 33.1 standard for EMI/RFI effects.
• Wide Operating Temperature: Ambient operating temperature range from -25 to +85°C.
• Protection Standards: IP67 (Standard). Optional explosion-proof ratings available: EEx ia IIC T5 and Ex d IIB T5.
