DTZ-OTG Transformer Temperature Controllers Smart Calibration System

Overview

    The DTZ-OTG Transformer Temperature Controller Smart Calibration System is designed for verifying transformer oil/winding temperature controllers, temperature switches, bimetal and pressure thermometers. Independently developed for high-volume testing, it delivers an intelligent, efficient batch calibration process.

    It supports simultaneous remote signal acquisition for 10 units under test, automatically calculating indication error, hysteresis error, repeatability error and inter-device deviation.

    With 10-channel thermal simulation and 6-channel contact detection, it accurately measures contact action error and differential gap.

Product Features

Integrates temperature controllers, electrical measuring instruments, test platform and wiring harness for efficient and accurate testing.

Product Functions

1. Calibration Functions

Supports three calibration types: indication, contact action and thermal simulation.

Multi-temperature point calibration for digital switching, indication and thermal analog signals, adapting to complex scenarios flexibly.

Indication calibration supports multi-temperature points, forward/reverse strokes and remote signals (PT100 3-wire/4-wire, active/passive current transmitters, RS485), with unlimited temperature points.

Superimposed Calibration: Simultaneously collects remote and contact action signals in one heating/cooling cycle, calibrates multiple items (indication error, hysteresis error, etc.) or separately.

2. Intelligence & Automation

Automatically matches test items and executes procedures per standards.

Indication calibration supports manual/automatic modes, with auto-capture, auto-recognition and unattended functions.

Automatically optimizes calibration point sequence for same-type thermometers with different ranges.

Intelligent Wiring Self-Check: Inspects wiring before startup and indicates error locations.

Voice/Music Alerts: Supports multiple prompt types (default, male/female voice, music).

3. Batch & Efficient Operation

Batch Calibration: Supports multiple wide-temperature thermostats and same-type different-range devices simultaneously, meeting high-volume demands.

Batch Information Entry: Batch input for identical tested devices to improve efficiency.

One-Click Task Copy: Duplicates calibration tasks for quick reuse with minor modifications.

One-Click Historical Import: Imports historical device info to avoid repeated entry.

Efficient Auxiliary Functions: Forced acquisition, pre-heating, power-off resumption, etc., reducing waiting time.

4. Data & Equipment Management

Full-Cycle Alerts: Expiration reminders for tested devices and standards via message center to ensure compliance.

User Management: Supports login and permission management for multi-user security.

Traceable Operation Logs: Automatically records operation details for audit and traceability.

Fast Historical Retrieval: Quickly searches, compares and traces historical calibration records.

Data Persistence: Database storage with separate record tables, managing devices, standards and templates.

5. Certificates & Reports

Supports generation, printing, preview and retrieval of certificates/raw records for easy traceability.

Word Export: Exports certificates/records to Word for editing and archiving.

Handwritten Signature: Embeds handwritten signatures for compliance and personalization.

6. Professional Tools & Expansion

Built-in thermal calculator supporting ITS-90 international temperature scale calculations.

Chinese-English interface switching without software restart.

Integrated test platform (temperature controllers, electrical instruments, etc.) for fast and accurate testing.
