Ztech's ZT502 Dual Channel Universal Process Indicator represents advanced monitoring technology designed for industrial applications requiring precise parameter indication. This robust instrument simultaneously displays two different process variables such as temperature, level, flow, or pressure with exceptional clarity using super bright 12.5mm LED displays. The universal input capability accepts signals from thermocouples (J, K, R, S, T types), RTDs (Pt100, Cu53), current (0-20mA), voltage, and millivolt inputs without requiring recalibration when switching between sensor types. With a measurement range from -1999 to 9999 and selectable decimal resolution, the ZT502 delivers accurate readings for virtually any industrial process requirement. The unit's flexible configuration allows for custom scaling, programmable hysteresis throughout the range, and sensor fail detection with user-definable responses.

The universal input capability accepts signals from thermocouples (J, K, R, S, T types), RTDs (Pt100, Cu53), current (0-20mA), voltage, and millivolt inputs without requiring recalibration when switching between sensor types. With a measurement range from -1999 to 9999 and selectable decimal resolution, the ZT502 delivers accurate readings for virtually any industrial process requirement. The unit's flexible configuration allows for custom scaling, programmable hysteresis throughout the range, and sensor fail detection with user-definable responses.

This process indicator serves critical roles across multiple industries including chemical processing, water treatment, oil and gas, pharmaceutical manufacturing, and power generation facilities. In chemical plants, it monitors reactor temperatures and pressures simultaneously, ensuring safe operation within specified parameters. Water treatment facilities utilize the dual channels for monitoring both flow rates and tank levels, while manufacturing plants employ it for process control and quality assurance. The device's rugged construction with ABS plastic enclosure and wide operating temperature range (-10 to 55°C) makes it suitable for harsh industrial environments where reliability is paramount. Optional weatherproof and flame-proof enclosures further extend its applicability to hazardous locations and outdoor installations.

The ZT502 delivers significant business value through its reliability, accuracy, and reduced maintenance requirements. Engineered with the latest technology and subjected to stringent quality tests, this instrument ensures long-term performance with ±0.1% accuracy for linear inputs and ±0.25% for non-linear inputs. The elimination of recalibration needs when switching input types reduces downtime and maintenance costs, while the front-key programmability allows quick configuration changes without specialized tools. Businesses benefit from the flexible power options (24VDC, 230VAC, or 90-260VAC/DC), multiple output configurations (up to 4 relay outputs per channel), and communication capabilities (RS232/RS485 Modbus RTU or GSM) that enable integration with existing control systems and remote monitoring solutions.

Key Features:
- Dual-channel universal input accepts thermocouples, RTDs, mA, mV, and voltage signals
- Super bright 4-digit 12.5mm LED displays with selectable decimal resolution
- Maximum 4 relay outputs per channel with 5A/230V contact rating
- Optional 4-20mA analog retransmission output with isolation
