Liquid Nitrogen Level MeasurementThe TEC 3000 uses a differential pressure system to determine the LN2 level to

an accuracy of ± 0.5 in. (15 mm) and a resolution of 0.1 in. (5.0 mm). Unlike

alternative level sensing systems, differential pressure allows the exact level to

be measured and displayed. Using the simple single point calibration in a range

of 3.0 in. to 48.0 in. (75 mm to 1220 mm), the patented, self-maintaining,

closed-loop system displays in inches, millimeters, or a percentage full.

Automatic Liquid Nitrogen Level ControlThe fully automated LN2 level control system is based on user-defined parame-

ters that can be electronically adjusted over the entire level range. The parame-

ters include Low Level Alarm, Low Level Fill Point, High Level Fill Point and

High Level Alarm. The redundant Dual Solenoid Valves for overfill protection

run on 24 VDC, 1.0 amp (max).

Liquid UsageThis exclusive feature provides an estimation of liquid usage to track LN2

consumption and can provide an early failure warning to allow sufficient time to

implement corrective action and save irreplacable samples.

User-Defined AlarmsA total of 17 audio/visual alarms are used to alert the user to any potential or

developing problems. The alarms include: High Temperatures, Low Tempera-

tures, High Level, Low Level, Liquid Usage, Maximum Fill Time, Gas Bypass,

Temperature Calibrations, Low Battery, Power Failure, Lid Open and Commu-

nication Loss.

Remote Alarm MonitoringThe TEC 3000 Alarm monitoring includes a Global Remote Alarm Relay, as

well as four discrete contacts for High Level, Low Level, Temp A High and

Low Battery.

The TEC 3000 employs a variety of advanced features that enable the controller to monitor and control the environment inside a freezer with a high level of precision.

Temperature MeasurementTwo independent temperature measurement channels are employed to

accurately measure the temperature across the entire storage space. The two

platinum RTD sensors have an accuracy of ± 1.0°C and a resolution of 0.1°C.

The temperature can be displayed in °C, °F or K. The single or two point cali-

bration also has altitude compensation for the highest accuracy.

Hot Gas BypassThis unique feature is able to vent warm nitrogen gas from the supply line be-

fore initiating a fill. This prevents warm gas from entering the freezer space,

which helps maintain a stable temperature gradient and increases the efficiency

by reducing excess LN2 evaporation.

Event Log / Data StorageThe TEC 3000 is able to store vital, unalterable, time-stamped data in

nonvolatile memory. This is a great tool for assessing freezer performance and

troubleshooting any problems. The memory can store 30,000 events, an

estimated 10 years of storage capacity. The data includes time-stamped

temperatures, LN2 level, liquid usage, and any alarms or events.

Password SecurityThe multilevel security system comprised of up to ten user-specific programma-

ble passwords and four security levels can be customized to grant or restrict

personnel access to certain menus and settings.

Communication CapabilitiesTwo independent ports can be used to communicate with other TEC 3000

controllers, a remote PC, serial printer, or other RS-485 networks and devices.

Cryopreservation Equipment Catalog

液体窒素レベル測定TEC 3000は差圧計を用いて精度±0.5 in.(15 mm)、分解能±0.1in.(5.0 mm)で液体窒素(LN2)レベルを測定します。差圧計は他のレベル検知システムとは異なり、正確なレベルの測定と表示が可能です。自動制御のクローズドループシステム(特許)が3.0in. 〜 48.0 in.(75 mm 〜 1220 mm)の範囲で1点較正を行い、インチ単位(ミリメートル単位)、または満充填レベルに対する割合(%)で値を表示します。

自動液体窒素レベル制御全自動のLN2レベル制御システムがユーザー設定のパラメーターに従って容器を制御します。設定できるパラメーターはLow LevelAlarm(下限レベルアラーム)、Low Level Fill Point(下限充填レベル)、High Level Fill Point(上限充填レベル)、High LevelAlarm(上限レベルアラーム)で、LN2レベルの全範囲にわたって電子的に調節できます。あふれ防止のために二重化されているソレノイド弁が24VDC、1.0アンペア(最大)で作動します。

使用液量この機能はLN2消費量を監視し使用液量の推定値を表示するので、早い段階での使用方法変更や再生不能な試料保護を行うことができます。

ユーザー設定アラーム17種類のアラーム音・アラーム表示で問題発生やその可能性を警告します。アラーム機能は以下の通りです:High Temperatures(上限温度)、Low Temperatures(下限温度)、High Level(上限レベル)、Low Level(下限レベル)、Liquid Usage(使用液量)、Maximum Fill Time(最大充填時間)、Gas Bypass(ガスバイパス)、 Temperature Calibrations(温度較正)、Low Battery(電池切れ)、Power Failure(停電)、LidOpen(フタ開放)、Communication Loss(通信遮断)

遠隔アラームモニターTEC 3000のアラームモニターは次の4個のパラメーターのいずれかが設定値を超えるとアラームが作動します。:High Level(上限レベル)、Low Level(下限レベル)、Temp AHigh(温度A上限)、Low Battery(電池切れ)

TEC 3000は容器内の状態を高い精度で監視・管理できる各種の高度な機能を備えています。

温度測定独立した2個の温度測定チャンネルを用いて容器内全体の温度を正確に測定します。2個の白金抵抗温度検出(RTD)センサーは精度が±1.0℃、分解能が0.1℃です。温度は摂氏(℃)、華氏(F)または絶対温度(K)で表示することができます。最高の精度を確保するために、1点較正または2点較正で標高補正も行います。

ホットガスバイパスこの機能により、液体窒素の充填を始める前にその供給ラインから窒素ガスを逃がし、凍結容器内に高温のガスが入らないようにすることができます。このため安定した温度勾配が保たれ、過剰なLN2蒸発を抑えるので効率が高まります。

イベントログとデータ保存TEC 3000は日時の記録された変更不可能な重要データを不揮発性メモリーに保存することができます。これは容器の性能評価やトラブル解決に役立ちます。メモリーには30,000件のイベントを保存でき、保存容量の目安はおよそ10年分です。次のデータが保存されます:日付時刻付き温度、LN2レベル、使用液量、アラームおよびイベント(発生した場合)

パスワードによる安全対策最大10個のユーザー別にプログラム可能なパスワードと4段階のセキュリティーレベルによる多重セキュリティーシステムを設定して、特定のメニューや設定の使用を許可したり制限したりすることができます。

通信機能2個の独立ポートを用いて他のTEC 3000コントローラーやリモートPC、シリアルプリンター、その他のRS-485ネットワーク・機器に接続することができます。次のオプションがあります:ASCII、MODBUS、プリンター、One Fill All Fill(OFAF)
