1. General Introduction
Tokyo Keiso FW-9000NN Servo Tank Level Transmitter is the successor to the well received and widely used FW-9000 series for its reliability and variety of long term application. Using the most of reliable, durable and highly accurate mechanism of FW-9000, FW9000NN has become more reliable and user-friendly by introducing up-dated electronics etc (SIL2 compatible). Consequently, FW9000NN has the interchangeability with the current FW-9000 series in terms of installation methods and interfaces with other equipment. Its noise resistivity and lightening protection performance have been improved significantly. The intensified automatic self-diagnosis and self-adjustment functions have made FW9000NN more user-friendly. Including ATEX certified version intended for use in potentially ex-plosive atmosphere FW9000NN is ready to serve world-wide users.
Added or improved features from existing models are listed as follows:
1.1 For bonded tanks
The increased noise resistivity and lightening protection assure you reliable operation as complying with superb level 4 or more stipulated in IEC61000-4,5.
1.2 Complying with RoHS requirements.
1.3 Having the same dimensions and materials as existing models, FW9000NN is compatible to Japanese explosion-proof requirements and is interchangeable with existing FW-9000 to make replacement easy.
1.4 Parameters can be set without opening housing with 4 magnet sensors attached to the indicating windows.
1.5 Compatible with wide range of power supply from 100 to 240 VAC, 50/60Hz.
1.6 Power source of 100 to 240 VAC 50/60Hz is acceptable
1.7 Standard 2 sizes of measuring drums cover wide measuring ranges from small to gigantic tanks
- Eco-friendly low power consumption as small as Max. 25VA.
- Covers high design pressure up to 3.0 MPa.
- Electronic circuits are installed in the electric compartment which is completely isolated from drum compartment.
- Can be connected to the existing spot type and multipoint aver-aging temperature sensors.
- Precision stepping motor control with micro processor has realized amazingly accurate measurement.
- Highly reliable operation with powerful self-diagnosis functions (SIL2).
- High durability with non-contact type balancer without using slip ring.
- In has addition to the high-speed serial data communication, FW9000NN have various communication tools which are com-patible to TOKYO KEISO's existing well-established transmitters. Therefore, FW-9000NN serves with ease for your renovation and replacement of the existing tank monitoring system.
- In combination with DIR110NN series, Max. 6 contact signals transmitted between field and control room. Monitoring and con-trol of equipments around the tank yard are also possible in addi-tion to liquid level measurement.
- 4 to 20 mA signals such as pressure signal can be digitalized and retransmitted
- Analog 4 to 20mA signals such as level and temperature can be output additionally to meet with high speed data processing car-ried by host computers.
