TCP2G250产品概述

Macromatic’s TCP Series Seal Leak & Temperature Relays protect submersible pump motors against damage from both seal leakage and over temperature. Two wires are connected to a resistive-sensing probe and common in the seal cavity to monitor for seal leakage. Two additional wires are connected to a N.C. thermal switch in the windings of the pump motor to monitor for over-heating. The product has isolated output contact relays, one for seal leak and one for over temperature. The over temperature set-point is fixed at 5K ohms. Two adjustable seal leak sensitivity ranges are available: 4.7K-100K ohms and 1K-250K ohms.

  • Monitors Submersible Pumps for Overtemperature & Seal Leakage
  • Two Adjustable Sensitivity Ranges for Seal Leak
  • Seal Leak Probe is Pulsed with a DC Voltage to Prevent Electroplating
  • Low-Profile Adjustment Knob
  • Full status indication on top of unit for easy troubleshooting
  • Uses industry-standard 11 pin octal sockets
  • Pilot Duty Rating

    Features:
  • 120V AC
  • 1K to 250K Ohms

    Specifications:
  • 7A @ 240V AC/5A @ 28DC
  • Dimensions: 3.0"D × 1.7"W × 2.4"H
  • Temperature: –28°C to +65°C

    Description of Function:
    Two wires are connected to a resistive-sensing probe & common in the seal cavity to monitor for seal leakage. Two additional wires are connected to a N.C. thermal switch in the windings of the pump motor to monitor for overheating. The product has isolated output contact relays, one for seal leak & one for temperature. The temperature set-point will be fixed at 5K ohms. Two adjustable seal leak sensitivity ranges are available: 4.7K-100K ohms and 1K-250K ohms.

    With input voltage applied, normal temperature condition (thermal switch closed) and no seal leak, the isolated temperature relay is energized and the isolated seal leak relay is de-energized. Both LED's are Green. When the motor temperature rises and the N.C. thermal switch opens, the temperature relay is de-energized, opening a contact that had been closed and turning off the pump contactor. The TEMP LED turns Red. If the seal starts to leak, contaminating fluid enters the seal cavity. This lowers the resistance between the internal probe & the common connection. When the resistance drops below the user-adjustable sensitivity set-point of the relay, the seal leak relay energizes and closes a contact, which can be used to give an alarm indication of a leaking seal. The LEAK LED turns Red. These products will automatically reset when the fault condition clears.
